Motorhome Buying Guide

Class A motorhomes are the largest, most luxurious, and most expensive type of motorhome. They're built on a commercial motor vehicle chassis — either a gas chassis (Ford F53 or GM P32) or a diesel chassis (Freightliner, Spartan, or Tiffin's proprietary chassis) — with the entire living unit constructed on top. Diesel Class As (diesel pushers) have the engine in the rear, which creates a quieter, smoother ride, more torque for hills, and better fuel economy on long hauls than gas Class As. They also typically have more storage in the basement (the exterior compartments below the floor) and are preferred by full-timers and frequent travelers. Gas Class As are more affordable ($80,000–$180,000 new vs. $150,000–$600,000+ for diesels) and are sufficient for occasional or seasonal use. The driving experience is more truck-like and less refined, but for buyers who aren't covering thousands of miles per year, the savings are significant.

Class C motorhomes are built on a cutaway truck chassis — the Ford E-450, Ram ProMaster, or Mercedes Sprinter are the most common — with the living unit extending behind and over the cab. The cab-over design creates a distinctive sleeping area above the driver and passenger seats, adding significant sleeping capacity in a compact footprint. Class Cs drive more like a large cargo truck than a bus, which most buyers find easier to manage than a Class A. They're available in lengths from about 20 to 37 feet, covering families, couples, and solo travelers. Mid-size models (26–30 feet) are the sweet spot for most buyers. Top Class C brands include Winnebago, Coachmen (Leprechaun, Freelander), Thor Motor Coach (Chateau, Quantum), and Forest River (Sunseeker, Solera). New models run $65,000–$150,000; used examples 3–7 years old are often found for $35,000–$80,000.

Beyond the standard RV inspection items (water damage, appliances, seals), motorhomes have chassis and mechanical components that require additional attention. For the engine, check all fluid levels, look for leaks under the engine, ask for maintenance records, and if possible have a mechanic inspect it independently. On diesel pushers, pay particular attention to the cooling system, air dryer, and air bags (if equipped). These are expensive repairs if deferred. On Class Cs, the Ford E-450 and GM chassis have excellent track records — but check the transmission service history specifically, as a transmission rebuild can cost $4,000–$8,000. Inspect the generator (if equipped): run it under load and check the hours. Generators typically need an overhaul around 1,000 hours. Check the coach batteries (usually four to eight 6-volt golf cart batteries or lithium units) for age and condition.
