When you shop for RV insurance, the class of your rig is the first thing that shapes your options. Class A, B, and C refer to the three main categories of motorized RVs, and each class has a distinct size profile, price range, and risk exposure that insurers price differently. On top of that, towable RVs like fifth wheels and travel trailers operate under a different insurance framework entirely. Understanding where your rig falls in this system tells you what coverage you need, which carriers can write the policy, and roughly what you should expect to pay.
Class A Motorhomes: The Largest and Most Expensive to Insure
Class A motorhomes are the big ones. Built on a commercial bus or heavy truck chassis, they range from about 26 feet to over 45 feet in length and can weigh 20,000 to 30,000 pounds fully loaded. Diesel pushers and gas-powered bus-conversion styles both fall into this category. These are the rigs with slide-outs, full kitchens, washer-dryer combos, and price tags from $100,000 on the low end to well over $500,000 for high-end diesel coaches.
Because Class A coaches are so large and expensive, they carry the highest insurance costs in the motorhome category. The collision exposure alone is significant. A Class A in an at-fault accident can cause catastrophic damage to other vehicles and infrastructure, and the repair cost on the coach itself can run $30,000 to $100,000 or more for a serious accident. Insurers treat Class A motorhomes closer to commercial vehicles than passenger cars when calculating rates, and the liability coverage requirements reflect that.
Comprehensive coverage on a Class A is also priced higher than smaller classes because the vehicle itself has more surface area exposed to weather events, more complex mechanical systems, and more expensive components. A hail storm that damages the fiberglass roof and sides of a 40-foot diesel pusher can generate a claim of $15,000 to $40,000 before repairs to awnings, satellite systems, and exterior slide components are included.
If you’re financing a Class A, the lender will require you to carry comprehensive and collision coverage with a deductible that meets their guidelines. Even if you own it outright, carrying physical damage coverage on a vehicle worth $150,000 or more is a straightforward decision. The liability minimums that work for a passenger car are completely inadequate for a vehicle this size and this expensive to operate.
Class B Motorhomes: Camper Vans and Lower Premiums
Class B motorhomes are built on a full-size cargo van chassis, most commonly Ford Transit, Mercedes Sprinter, or Ram ProMaster. They’re compact by motorhome standards, running 18 to 24 feet in length, and they’re the lightest and most maneuverable of the three motorhome classes. Think converted cargo vans with sleeping quarters, a compact kitchen, and a basic wet bath — sometimes a toilet, sometimes not.
Because Class B vehicles are mechanically similar to passenger vans, they’re often insured through standard auto insurers rather than specialty RV carriers. The premium profile is lower than Class A for multiple reasons: the vehicles are smaller and cause less damage in collisions, they’re easier to repair, replacement parts are typically available through standard automotive channels, and the purchase price is lower (though new, purpose-built Class B vans from companies like Airstream or Winnebago can still hit $150,000 to $200,000).
One area where Class B owners sometimes get caught is the gap between insuring the vehicle as a cargo van versus insuring it as an RV. If you converted a cargo van yourself and you’re using it as your primary travel vehicle, a standard auto policy may not correctly cover the custom buildout inside. Specialty RV insurers offer agreed-value coverage that accounts for the custom interior, the solar systems, lithium battery banks, and cabinetry that a standard auto policy would never pay to replace. If you have a custom Class B build worth more than the van itself, this coverage matters.
Liability rates for Class B vehicles are also lower than Class A. A 20-foot van doesn’t carry the same collision damage potential as a 40-foot bus, and insurers price that difference into the liability premium.
Class C Motorhomes: The Middle Ground
Class C motorhomes are built on a cutaway truck chassis with an over-cab sleeping area extending forward over the cab section. They’re easily recognizable by that distinctive cab-over bunk. They range from about 20 to 33 feet in length and typically cost between $60,000 and $160,000 new, though older units can be found for far less.
Class C insurance falls between Class A and Class B in cost. They’re large enough that standard auto insurers often won’t write them, pushing buyers toward RV specialty carriers or insurers with dedicated RV divisions. But they’re more manageable than Class A in terms of collision exposure and repair cost, so premiums reflect that middle-ground profile.
One Class C-specific consideration is the cab-over section. That front sleeping area is fiberglass and tends to take damage in low-clearance incidents — drive-throughs, parking garage entrances, tree branches you misjudged. These incidents generate comprehensive or collision claims that are expensive to repair because of the fiberglass work required and the labor involved in blending paint on curved surfaces. If you’re new to RV driving, this is a vulnerability to understand before you park in an unfamiliar lot.
Class C motorhomes are also popular as rental units and for families that want more space than a Class B but aren’t ready for a full Class A. That broader user base means more underwriting options, more competition among insurers, and generally better pricing than you’d find for Class A motorhomes at comparable coverage levels.
Towable RVs: Fifth Wheels and Travel Trailers
Fifth wheels and travel trailers sit in a completely different insurance category from motorhomes because they don’t move under their own power. A fifth wheel is towed by a pickup truck using a fifth-wheel hitch mounted in the truck bed. A travel trailer is towed by a ball hitch on a passenger vehicle or truck. Both are non-motorized, and that single fact changes the insurance structure significantly.
When a towable RV is in transit, the tow vehicle’s auto insurance is the primary coverage for liability. If you cause an accident while towing your fifth wheel and injure someone, your truck’s auto liability policy responds. The trailer itself doesn’t need its own liability coverage while it’s moving down the road, because the tow vehicle’s liability extends to the trailer it’s pulling in most states and under most policies.
Where towable RV insurance comes in is physical damage coverage for the trailer itself. Your truck’s auto policy may extend comprehensive and collision coverage to the trailer while it’s being towed, but the coverage often doesn’t follow the trailer when it’s unhitched and parked at a campground. A standalone RV policy for a towable unit provides physical damage coverage regardless of whether the trailer is hitched or parked — fire, theft, hail, vandalism, and accident damage are all covered.
Fifth wheels are generally more expensive to insure than travel trailers because of their larger size and higher purchase price. A luxury fifth wheel can cost $80,000 to $150,000, putting it in a price tier where the physical damage premium is meaningful. Travel trailers range from inexpensive pop-ups and teardrop trailers under $15,000 to fully loaded 32-foot units over $60,000. Premiums scale accordingly.
Coverage Types Unique to Motorized RVs
Because Class A, B, and C motorhomes drive under their own power, they need coverage types that towable RVs simply don’t require. Roadside assistance for a motorhome is different from roadside assistance for a car. A Class A diesel pusher that breaks down on the side of the highway requires a large-vehicle capable tow truck, and those aren’t always easy to find depending on where you are. RV-specific roadside assistance programs through carriers like Good Sam, Progressive, or National General include towing to the nearest qualified repair facility, which may be 50 to 100 miles away for a specialty coach.
Emergency expense coverage is another motorhome-specific provision. If your Class A breaks down 400 miles from home and needs a week in the shop, you need a place to stay and a way to get around. Emergency expense coverage pays for lodging and transportation while the rig is being repaired, up to a daily limit and overall cap. This is included in many RV policies or available as an endorsement, and for full-size motorhomes it can cover real costs that would otherwise come out of pocket.
Total loss replacement is a coverage option for newer motorhomes that replaces the vehicle with a new unit rather than paying the depreciated actual cash value. Given how quickly motorhomes depreciate, this can be a meaningful difference in a total loss scenario. A Class A that cost $250,000 two years ago may be worth $180,000 in actual cash value today. Total loss replacement would provide enough to buy the equivalent new unit rather than absorbing the depreciation gap yourself.
How Much More Does Class A Insurance Cost Than Class B or C?
The premium difference between classes is real but varies based on vehicle value, driver history, usage patterns, and state. As a general framework: a Class B camper van with a value of $80,000 might run $1,200 to $2,000 per year in full coverage. A Class C at $100,000 in value might run $1,500 to $2,500. A Class A diesel pusher at $250,000 might run $3,000 to $5,000 or more per year, particularly if it’s a high-end coach with expensive slide mechanisms, custom interior, and a diesel drivetrain that costs significantly more to repair than gas engines.
Usage is a major pricing factor that applies across all classes. An RV used 30 days per year for weekend camping carries far less exposure than one used full-time as a primary residence. Carriers ask about usage when underwriting, and the premium reflects it. If you transition from recreational use to full-time living, you need to tell your insurer. Policies written for recreational use typically have exclusions or coverage gaps that make them inadequate for full-time occupancy.
Storage discounts are available through many carriers for seasonal RV users. If you park your Class A in covered storage from November through March, some carriers will reduce your premium during that period because the exposure — particularly collision and liability — is reduced when the vehicle isn’t being operated. Ask your agent whether your carrier offers a storage discount and what usage restrictions apply during the storage period.
Matching Coverage to Class
The right coverage level tracks directly to the class and value of your RV. For a Class A worth $200,000 or more, you want agreed value or replacement cost coverage, high liability limits (at least $500,000, ideally $1 million), vacation liability for campsite coverage, full roadside assistance with large-vehicle capability, and emergency expense coverage. For a Class B camper van, an agreed value policy that covers the custom buildout, good liability coverage, and roadside assistance are the priorities. For a Class C, full physical damage coverage, reasonable liability, and coverage for that vulnerable cab-over section should be on your checklist.
Towable RVs need physical damage coverage that stays with the trailer whether it’s hitched or parked, vacation liability for campsite exposure, and contents coverage for the gear, electronics, and personal belongings stored inside. The tow vehicle handles liability while in transit, but the trailer needs its own policy to be fully protected.
The class of your RV is the foundation of how your policy is built. Getting the class right with your insurer, disclosing your actual usage accurately, and building coverage appropriate to the vehicle’s value are the basics that everything else rests on. Work with a broker who writes multiple RV carriers so you’re getting options rather than whatever one company happens to offer.
