What to Expect

Watch the Cab-Over — and Everything Else

A Class C is built on a truck or van chassis (Ford E-Series, Mercedes Sprinter, Chevy Express, sometimes a Ford F-450 cutaway) with the coach mounted behind the cab and a sleeping area extending up and over the cab roof. It's the most popular drivable RV in the country — and the cab-over bunk is the most common location of water damage in any RV.

Scott's Class C inspection puts extra attention on the cab-over junction, the front-cap seal, and every roof seam — but it's still a full inspection of the chassis, slide-outs, roof, electrical, plumbing, propane, HVAC, and every system in the coach.

After the inspection you receive a detailed written report with photos delivered the same day.

Inspection Coverage

What We Inspect on a Class C

Truck or Van Chassis

Ford E-Series, Sprinter, Chevy Express, or Ford F-450 cutaway. Engine compartment, transmission, brakes, suspension, tire age, and a service record review.

Cab-Over Bunk & Front Cap

The #1 inspection point on a Class C. The seam where the coach meets the cab is checked for sealant cracking and moisture entry. The cab-over bunk floor and walls are checked for soft spots that indicate prior water damage.

Roof Seals

Full roof walk. Every vent, AC unit, antenna, skylight, and slide-out roof are checked. The front-cap and rear-cap roof seams are critical.

Slide-Outs

Most Class C's have 1 or 2 slides. Each is operated through a full cycle and the floor and roof seals are inspected.

Coach Electrical

House batteries, converter, inverter (if equipped), transfer switch, every 120V outlet, GFCI testing, shore-power inlet.

Generator (If Equipped)

Onan or Cummins onboard generator — hours, oil, fuel, exhaust, slide-tray, and load test if operational.

Propane, Plumbing, HVAC

Propane regulator and detector, fresh/gray/black tanks and valves, water pump, water heater, AC and furnace operation.

Appliances

Refrigerator (3-way or 12V compressor), microwave, range, awning, all interior fixtures.

Interior Walkthrough

Every cabinet, drawer, window, blind, and slide trim — looking for signs of past water entry, soft floors, or deferred maintenance.

Common Questions

Class C Motorhome — Frequently Asked Questions

What is the appeal of a Class C over a Class A?
A Class C gives you the familiar, comfortable driving feel of a van cab while still delivering a full-size RV living space behind it. Many buyers prefer the visibility and maneuverability of sitting in a van-style cab rather than the large flat front of a Class A. At the same time, a Class C can be just as spacious inside as many Class A coaches, making it a compelling middle-ground option.
How many people can sleep in a Class C?
Class C coaches are among the best RV types for sleeping capacity. The bunk above the cab sleeps two people. Many models also include a dinette that converts to a bed, a sofa that converts to a bed, and a rear bedroom. Depending on the floor plan, a Class C can comfortably sleep six or more people, making it popular with families.
Do Class C motorhomes have airbags?
Most newer Class C's will have airbags in the van portion of the coach. The safety advantages of these airbags often goes unmentioned. Because a Class C is built on a van cab—Ford, Mercedes-Benz, or similar—the front occupants benefit from the full airbag system and reinforced metal cab structure that came with that vehicle from the factory. In a rollover or frontal collision, the two front seat passengers have the same passive safety protection they would have in any modern van. Most Class A motorhomes, by contrast, do not have airbags—the cab is a custom coach body rather than an automotive platform. Class B vans share this same safety advantage with Class C for the same reason. For buyers prioritizing passenger safety, this is a meaningful distinction worth knowing.
What kind of fuel economy can I expect from a Class C?
Fuel economy on a Class C depends heavily on the chassis. Ford and Chevrolet gas engine platforms — which power the majority of Class C coaches — are large engines and typically deliver under ten miles per gallon. If you are covering significant miles, that adds up quickly. The Mercedes-Benz Sprinter chassis offers a diesel engine option that delivers meaningfully better fuel economy than the gas platforms, making it worth considering for buyers who plan to travel frequently or cover long distances. Fuel cost over the life of the coach can be a significant factor, and the Sprinter diesel advantage is real enough to influence the buying decision for high-mileage travelers.
What is the biggest inspection concern on a Class C?
Water intrusion is always a major concern on any RV. Water could enter the coach through numerous places if the sealant isn't proper or maintained over time. Some class C's come with a full fiberglass upper bunk areas which require less sealant. Water intrusion is often invisible to the naked eye from both inside and outside the coach. During an inspection I do not remove wall panels. In most cases I can just use a moisture meter to compare one area with another in the same coach. Moisture meters aren't perfect but if an area shows suspected moisture, it warrants further investigation after the inspection.
Can a Class C go off-road?
Class C motorhomes are not designed for off-road use. One of the limiting factors is the departure angle at the rear — the distance from where the rear tires contact the ground to the bottom of the rear bumper is too long to allow meaningful off-road capability without dragging. While a very small number of Class C models offer four-wheel drive, they are rare, and even with four-wheel drive the departure angle remains a significant constraint. Class C coaches are best kept on paved or well-maintained roads.
Are the front cab seats usable as living space when parked?
Many manufacturers try to make the front two seats swivel to face the living area when parked, turning them into additional seating. In practice, this works better in some configurations than others. Ford-based Class C coaches tend to have lower seat positions that make it difficult to get up from when facing rearward. Sprinter-based models have addressed this somewhat with higher seat positions and cushion inserts. Even so, integrating the cab into the living space remains a challenge across most Class C designs.
What is the difference between a Ford van cutaway and a Sprinter-based Class C?
A Ford cutaway Class C uses a Ford E-Series or F-Series cab and chassis, which is a tried and true platform with widely available service and parts. A Sprinter-based Class C uses a Mercedes-Benz Sprinter van cab, which offers a more car-like driving experience, better fuel economy in some cases, and a higher seating position. Sprinter service requires a Mercedes dealer or specialty shop, which can be harder to find in some areas. Both platforms have their strengths, and the choice often comes down to personal preference and where you plan to travel.
