Vans & Chassis

Sprinter Van
Mercedes-Benz's full-size van platform, prized by coachbuilders for its turbo-diesel drivetrain, high-roof options, and refined road manners. It is the foundation for most of the luxury conversions Auto Elite builds.
Wheelbase (144 vs. 170)
The distance in inches between the front and rear axles. The Sprinter comes in 144-inch and 170-inch wheelbases; the 144 is easier to park, the 170 offers far more interior room. See our guide to choosing the right wheelbase.
170 Extended (170 EXT)
The longest Sprinter configuration, adding roughly a foot of body length behind the 170-inch wheelbase. Maximum floor space for full bathrooms, garages, and multi-zone lounges.
High Roof
A factory roof option giving most adults full standing height inside the van, generally about 6 feet 4 inches of interior clearance. Nearly all luxury conversions start with a high-roof chassis.
Cargo Van
A Sprinter delivered as an empty steel shell with no rear windows or seating. The blank canvas most custom conversions begin from.
Crew Van
A factory configuration with one row of rear seating plus cargo space behind, a middle ground between cargo and passenger vans.
Passenger Van
A Sprinter factory-built with full seating and windows. Executive upfitters often replace factory seats with captain's chairs and custom interiors.
Ford Transit
Ford's full-size van platform, available with AWD and an EcoBoost gas engine. A popular Sprinter alternative; Auto Elite offers Ford Transit conversions.
Ram ProMaster
Stellantis's front-wheel-drive full-size van, known for its wide, squared cargo box and lower load floor. Auto Elite builds Ram ProMaster conversions as well.
Class B RV (Camper Van)
The RV industry's designation for a motorhome built within a van body, like a converted Sprinter. Easier to drive and park than larger Class A or C motorhomes while still offering sleeping, cooking, and bath facilities.
Class B+
A motorhome slightly larger than a Class B, typically built on a cutaway van chassis with a widened body. Sits between a camper van and a Class C in size.
GVWR
Gross Vehicle Weight Rating: the maximum the van can legally weigh fully loaded, including passengers, gear, and fluids. Vans over 6,000 pounds GVWR may qualify for accelerated business tax deductions - see our tax savings page.
Payload
How much weight the van can carry: GVWR minus the vehicle's empty (curb) weight. Conversions consume payload, so quality builders weigh and balance every build.
Curb Weight
The weight of the finished vehicle with all fluids but no passengers or cargo.
Dually (DRW)
Dual rear wheels. Found on heavier-duty Sprinter 3500/4500 chassis, increasing payload capacity and stability for large or heavily equipped builds.
AWD / 4x4
All-wheel-drive and four-wheel-drive systems that send power to all four wheels for confidence in snow, sand, and gravel. Late-model Sprinters use an automatic AWD system; earlier vans offered a selectable 4x4.
MBUX
The Mercedes-Benz User Experience infotainment system: touchscreen navigation, voice control, and smartphone integration found in current Sprinter cockpits.

Conversion & Coachbuilding

Conversion Van
A van professionally transformed after leaving the factory - new seating, cabinetry, power, climate, and entertainment systems - to serve as a luxury cruiser, executive office, camper, or shuttle.
Upfitter
A company that modifies factory vehicles with new equipment and interiors. Often used interchangeably with coachbuilder, though upfitting can be as simple as shelving and as elaborate as a full luxury coach.
Coachbuilder
A manufacturer that hand-crafts complete custom vehicle interiors and bodywork, the tradition Auto Elite works in at its Elkhart, Indiana factory.
Second-Stage Manufacturer
The legal term for a company that completes or alters a vehicle after the original manufacturer, taking responsibility for the added systems' compliance with federal safety standards.
Floor Plan (Layout)
The arrangement of seating, galley, bath, bed, and storage along the van's length. The single most important decision in a custom build, set early in the design process.
Spec Build
A van built to a proven specification and offered for sale ready to drive, the fastest way into a luxury conversion. Browse current spec builds in our inventory.
Custom Build
A van designed around one buyer: layout, materials, power, and technology selected to order. Start one with Build Your Vehicle.
Build Sheet
The documented specification of everything in a conversion - chassis options, systems, finishes, and serial-numbered components. Important for service, insurance, and resale.
RVIA Certification
A seal from the RV Industry Association indicating a motorhome was built to the ANSI/NFPA 1192 standard for plumbing, propane, and electrical systems.
FMVSS
Federal Motor Vehicle Safety Standards. Reputable conversion companies use seating and restraints engineered and tested to these standards - a key difference between professional builds and DIY interiors.
CNC Cabinetry
Cabinet components cut by computer-controlled machinery for repeatable, furniture-grade precision, then hand-finished and fitted to the van's curves.
Marine-Grade Materials
Plywoods, fabrics, and hardware engineered to resist moisture, vibration, and UV exposure, borrowed from yacht building and standard in quality van conversions.
Sound Deadening
Butyl or composite damping layers applied to the van's steel panels to cut road noise and resonance before insulation and paneling go in.
Insulation
Thermal and acoustic material - commonly Thinsulate, wool, or closed-cell foam - installed within the van's walls, floor, and ceiling for year-round comfort.
Headliner
The finished ceiling surface of the van. In luxury builds, often upholstered suede or leather-look material, sometimes with fiber-optic starlight lighting.
Valance
A trim panel that conceals window shade tracks, lighting strips, or curtain hardware where walls meet the ceiling.
Partition Wall
A dividing wall inside the van, used to separate a driver's cab from a lounge, create a private rear suite, or enclose a bathroom.
Roof Rack & Ladder
Exterior systems for carrying gear, awnings, and solar panels, engineered for the high-roof van's height and wind loads.

Interior & Comfort

Captain's Chairs
Individual armchair-style seats, often heated, ventilated, powered, and reclining in luxury builds. The signature seating of executive Sprinters.
Swivel Seats
Cab seats mounted on rotating bases so the driver and passenger chairs turn to face the living or meeting space when parked.
Pullman-Style Seating
Facing rows of seats, train-compartment style, that convert between conference seating and lounge or sleeping configurations - as in the Auto Elite Elite Pullman.
Sofa Bed / Convertible Lounge
A rear bench engineered to fold flat into a bed, frequently power-actuated in luxury conversions.
Murphy Bed
A bed that folds up against the wall or cabinetry when not in use, freeing daytime floor space.
Galley
The van's kitchen area: countertop, sink, refrigeration, and cooking surface, often an induction cooktop in modern all-electric builds.
Wet Bath
A sealed bathroom where the shower shares the space with the toilet and sink, the most space-efficient way to get a full bath into a van.
Dry Bath
A bathroom with a separate, enclosed shower stall, found in larger 170 and 170 EXT floor plans.
Removable Bathroom
A self-contained bathroom module that can be taken out of the van to free up cargo or seating space, a hallmark of Auto Elite models like the Road Jet and Elite Cruiser.
Cassette Toilet
A toilet with a removable waste tank that can be emptied at a dump station or household toilet, avoiding the need for permanent black-tank plumbing.
Garage
Van-speak for the rear cargo area beneath or behind the bed, sized for bikes, golf bags, skis, or luggage. The Road Liner 737 is built around a massive one.
Blackout Shades
Light-sealing window coverings, often magnetic or track-mounted, for privacy and true darkness when sleeping.
Ambient Lighting
Dimmable, often color-adjustable LED lighting layered through ceiling, toe-kick, and cabinet zones to set the cabin's mood.
Starlight Headliner
Hundreds of fiber-optic points woven through the headliner to mimic a night sky, a Maybach-inspired touch available in ultra-luxury builds like the Road Liner Limousine.
Fold-Out TV Lift
A motorized mechanism that stows a television flush within cabinetry or the headliner and presents it at the touch of a button.
Privacy Glass (Limo Tint)
Deeply tinted, often laminated glass that conceals the cabin and reduces heat, standard on executive and limousine builds.
12V Refrigerator
A compressor refrigerator that runs efficiently on the van's battery system, unlike absorption fridges that need propane or shore power.
Power Sliding Door
A motorized side entry door that opens and closes at the touch of a key fob or interior button, an executive-van staple.

Power & Off-Grid Systems

House Battery
The battery bank that powers the living space - lighting, refrigeration, outlets, climate - independent of the engine's starting battery.
Lithium (LiFePO4) Battery
Lithium iron phosphate house batteries: lighter, faster-charging, and far longer-lived than lead-acid, with usable capacity across nearly their full charge range. The modern standard in luxury builds.
Inverter
Converts the battery bank's 12-volt DC power into 120-volt AC household power for outlets, appliances, and electronics.
Inverter/Charger
A combined unit that inverts battery power to AC and, when plugged into shore power, recharges the batteries and passes power through to the coach.
Shore Power
Plugging the van into an external electrical source - a campground pedestal or garage outlet - to run systems and charge batteries.
Solar Array
Roof-mounted panels that recharge the house batteries from sunlight. Auto Elite's Eco Evolution and Eco Revolution are designed around solar-first power.
Charge Controller
The device that regulates solar panel output so it charges the battery bank safely and efficiently, usually an MPPT type in quality systems.
DC-DC Charger
Charges the house batteries from the engine's alternator while driving, with the correct charge profile for lithium banks.
Second Alternator
A dedicated engine-driven alternator that rapidly recharges large lithium banks, capable of replenishing hours of power during a drive.
Battery Isolator
Prevents the house system from draining the engine's starting battery, so the van always starts no matter how the coach was used overnight.
Off-Grid / Boondocking
Camping without hookups, relying on the van's own batteries, solar, water, and tanks. Generous lithium-plus-solar systems are what make true off-grid luxury possible.
Full Hookups
A campsite offering electric, water, and sewer connections at the site.
Underbody Generator
A compact generator mounted beneath the van that provides AC power and charging without sacrificing interior space.
Diesel Heater
A furnace that sips fuel from the van's own diesel tank to deliver quiet, thermostat-controlled heat without engine idling.
Hydronic Heating
A system that circulates heated fluid to provide cabin warmth and hot water from one unit, the premium approach to four-season climate.
Roof Air Conditioner
A low-profile AC unit mounted on the roof; modern soft-start and inverter-driven units can run from a healthy lithium bank.
Fresh / Grey Water Tanks
Fresh water feeds the sink and shower; the grey tank collects drain water until it can be emptied at a dump station.
Tankless Water Heater
Heats water on demand as it flows rather than storing a heated tank, saving space, weight, and energy.
Power Awning
A motorized awning that extends from the van's side at the push of a button, often with wind sensors that retract it automatically.

Driving, Safety & Performance

Air Ride Suspension
Adjustable air springs that level the van, smooth the ride, and can lower the body for easier entry. Available as an Auto Elite upgrade.
Lift Kit
Suspension components that raise the van's ride height for greater ground clearance and larger all-terrain tires.
Crosswind Assist
A Sprinter stability feature that automatically counteracts strong side gusts on highways and bridges.
Active Safety Suite
Driver-assistance technology - adaptive cruise, lane keeping, blind-spot monitoring, collision mitigation - available on modern Sprinter, Transit, and ProMaster chassis.
360-Degree Camera
A multi-camera system that stitches a top-down view of the van's surroundings, invaluable when parking a 20-plus-foot vehicle.
Armored Sprinter
A Sprinter discreetly fitted with ballistic protection - opaque armor, transparent armor (glass), and reinforced systems - for executive security. Auto Elite builds executive and armored vehicles to client specifications.
Run-Flat Tires
Tires engineered to travel a limited distance after losing pressure, commonly paired with armored builds.
Turning Radius
How tightly the van can turn. The 144 wheelbase turns markedly tighter than the 170, one reason urban owners favor it.
Height Clearance
A high-roof Sprinter stands roughly 9 to 10 feet tall with roof equipment. Owners learn their exact number and watch for parking garages and drive-throughs.
Towing Capacity
How much trailer weight the van is rated to pull, commonly up to about 5,000 pounds on properly equipped Sprinters.
Hitch-Mounted Trunk
A weatherproof cargo box that mounts to the rear receiver hitch, adding secure storage without a trailer. See Auto Elite's hitch-mounted trunk.
Fiberglass Backpack Trunk
A molded fiberglass storage pod fitted to the rear of the van, color-matched and lockable. An Auto Elite signature upgrade.
Wheelchair Lift Conversion
A mobility-equipped van with a powered lift, secured wheelchair positions, and accessible interior dimensions, like the Auto Elite Mobility Sprinter.

Buying, Ownership & Business Use

MSRP
Manufacturer's Suggested Retail Price. For conversions, the completed vehicle's price reflects both the chassis and the coachwork.
Chassis Warranty
The original manufacturer's warranty covering the engine, drivetrain, and factory systems, honored at Mercedes-Benz, Ford, or Ram dealers nationwide.
Conversion (Upfit) Warranty
The coachbuilder's coverage of the systems and craftsmanship it added. Always ask any builder what is covered, for how long, and how claims are handled.
Section 179 Deduction
A federal tax provision letting qualifying businesses deduct a substantial portion of a work vehicle's cost in the year it enters service; many executive van buyers qualify. Learn more on our tax savings page and consult your tax professional.
Bonus Depreciation
An additional accelerated depreciation allowance that can stack with Section 179 for business vehicles. Rules change year to year - verify current limits with your accountant.
Business Use Percentage
The share of a vehicle's mileage used for business, which determines how much of its cost is deductible. Documentation matters.
Livery
Operating a vehicle for hire with a driver - executive shuttles, hotel transfers, tour services. Livery use has its own insurance and licensing requirements. Auto Elite's executive shuttles and 15 Passenger Coach are built for this work.
Lead Time
The time from signed purchase order to completed vehicle. Custom builds are scheduled into production slots; spec builds in inventory can deliver quickly.
Purchase Order & Deposit
The signed agreement specifying your build and price; a deposit typically reserves your production slot before construction begins.
Factory Pickup
Taking delivery at the builder's facility - at Auto Elite, that means a walkthrough of your van where it was crafted in Elkhart, Indiana.
White-Glove Delivery
Having the finished van delivered to your door - by transport carrier or a professional driver - with a full orientation, available anywhere in the USA.
Trade-In
Applying your current vehicle's value toward a conversion purchase. Contact our team to discuss options.
RV Financing
Loans structured for motorhomes and conversion vans, often with longer terms than auto loans. Start with our financing application.
Title & Registration Class
Depending on the build and your state, a conversion may title as a passenger van or a motorhome, which affects registration, insurance, and sometimes taxes. Your state DMV has the final word.
Resale Value
Professionally built conversions from established coachbuilders hold value better than DIY builds, thanks to documented systems, safety-compliant seating, and brand reputation.
