Small Motorhomes Guide 2026: Sizes, Prices and Small Motorhomes for Sale

If you have been searching rv motorhome small and getting nothing but 35-foot diesel pushers, this guide is for you. Small motorhomes — the 17 to 25 foot rigs most people call camper vans or Class B RVs — are the fastest growing slice of the US RV market, and for good reason: they park in a normal space, they return roughly double the fuel economy of a big coach, and you can daily-drive one without planning your route around turning circles.

But “small” hides a wide range. A 17-foot ProMaster conversion and a 25-foot Class B+ coach are both sold as small motorhomes, and they suit completely different owners. This guide breaks down the sizes, the real 2026 prices, the running costs nobody advertises, and the inspection points that separate a good buy from a $70,000 lesson.

Quick facts about small motorhomes

• Length: 17–25 ft, versus 30–45 ft for a Class A
• Fuel economy: commonly 14–22 MPG, versus 6–10 MPG for a large coach
• Licence needed: a standard driver’s licence in every US state, since GVWR stays under 26,000 lb
• Sleeps: 2 comfortably, 3–4 with a pop-top or convertible dinette
• Fresh water: typically 20–40 gallons, versus 80–100 on a big rig
• Campground access: fits nearly every national and state park site, most of which cap out between 25 and 30 ft
• Storage: fits most residential driveways, avoiding $100–$250 a month in RV storage fees

What counts as a small motorhome?

There is no legal definition, so dealers classify by length and chassis. In practice a small motorhome falls into one of four buckets.

Class B (17–23 ft)

Built entirely inside an existing van body — Mercedes Sprinter, Ford Transit or Ram ProMaster. Nothing sticks out beyond the original silhouette, which is why a Class B drives like a tall van rather than a truck. This is the truest small motorhome camper and the segment growing fastest. Browse live examples in our Class B RV and camper van listings.

Class B+ and small Class C (23–26 ft)

A van cab with a widened, purpose-built body behind it. You gain a proper dry bath, a fixed bed and far more storage, but you lose the ability to park in a normal space and you add a cab-over section that catches crosswinds. Most factory coaches from established RV manufacturers live here.

Truck campers and pop-tops (under 20 ft)

The lightest way in. A pop-top adds a second sleeping berth without adding length, which is why families on a budget gravitate to them. The trade-off is insulation — canvas sides are cold in shoulder season. See vans with poptops for current examples.

Custom van conversions

Professionally built one-offs on a cargo van chassis. Often the best specification for the money — lithium power, diesel heat, real insulation — but resale depends entirely on whether the builder is known and the work documented.

Small motorhome sizes and what actually fits

If you mostly travel as a couple, the sweet spot is 19–22 ft — see camper vans for 2 people. Families should start at the 170″ extended builds in our long wheelbase van collection or the four-berth options under camper vans for a family of 4. Anyone prioritising city parking should look at short wheelbase vans.

What small motorhomes cost in 2026

Budget rule of thumb: a new Class B small motorhome lands between $80,000 and $200,000; a clean 3–6 year old example typically saves 25–40%.

Price bands explained

• $45,000–$80,000 — entry used. Older chassis, basic 12V systems, lead-acid batteries, often a portable or cassette toilet and no interior shower. Expect to spend $5,000–$15,000 bringing the electrical and water systems up to modern standard.
• $80,000–$130,000 — the volume segment. Gas Transit or ProMaster base, 200–400 Ah lithium, 200–400W solar, wet bath, induction cooking, diesel or propane heat. This is where most first-time buyers land and where the widest choice sits.
• $130,000–$200,000 — premium. AWD diesel Sprinter, 8–12 kWh lithium, diesel air heat, interior shower, four-season insulation, often a rear garage for bikes and gear.
• $200,000+ — bespoke. Custom off-grid and luxury camper van builds with high-end cabinetry, oversized battery banks and expedition suspension.

The costs buyers forget

1. Insurance — $900–$2,400 a year depending on state, value and whether you full-time. Critically, the policy must cover the conversion value, not just the chassis. Get this quoted in writing before you buy.
2. Annual maintenance — budget $1,200–$2,500 for chassis service, plus roof resealing every 3–5 years.
3. Tyres — commercial LT tyres run $250–$400 each and must be replaced on age (5–7 years) regardless of tread depth.
4. Depreciation — steepest in years one to three. This is exactly why buying a lightly used rig is usually the smarter play.
5. Campground fees — $35–$90 a night at developed sites, though small motorhomes can boondock far more easily than big coaches.

Run the numbers before you fall in love with a listing — our payment calculator shows the monthly cost at different down payments and terms. Remember that RV loans commonly stretch to 10–15 years, which makes an expensive rig feel deceptively affordable while quietly adding tens of thousands in interest.

Small motorhome campers vs large RVs

Two practical notes. First, most national park campgrounds cap sites around 25–30 ft, so staying under 22 ft opens almost the entire system — check limits on the National Park Service camping pages before you book. Second, you can compare the actual EPA figures for any specific chassis and model year at fueleconomy.gov rather than trusting a seller’s estimate.

Which chassis should your small motorhome be built on?

• Mercedes Sprinter — tallest interior, factory AWD, 400–500 mile diesel range, strongest resale. Highest service costs and dealer-concentrated support. See Sprinter camper vans for sale.
• Ford Transit — AWD available, cheapest nationwide service, excellent parts availability, gas only. Usually $20,000–$40,000 less than an equivalent Sprinter build. See Transit camper vans.
• Ram ProMaster — front-wheel drive, widest flat floor, lowest load height, cheapest to buy. No AWD option. See Ram / ProMaster listings.

The honest summary: the chassis matters less than the quality of the conversion. A well-documented ProMaster build will serve you better than a poorly executed Sprinter one, and cost far less.

What to check before you buy

1. Water intrusion — inspect roof penetrations, fan flanges, solar mounts and window seals. Use a moisture meter on the walls beneath each one. Soft spots or brown staining mean walk away; water damage in an RV is rarely a cheap fix.
2. Electrical build quality — fused, labelled, correctly gauged wiring, with a diagram. Run the inverter, fridge and heater simultaneously for twenty minutes and watch the voltage.
3. Battery age and cycles — a lithium bank is a $4,000–$9,000 replacement. Ask for install date and cycle count, not just “it holds charge”.
4. Plumbing under pressure — fill, pressurise, run every tap, then drain completely while looking underneath for drips.
5. Heater from cold — a diesel or propane heater that only lights when already warm is telling you about a fault you will pay for in October.
6. Chassis history — check open recalls free by VIN at NHTSA, and get service records.
7. Remaining payload — compare the door-sticker GVWR to actual weight at a public scale. Many heavy builds leave under 500 lb, which two adults, water and gear will exceed immediately.
8. Who built it — factory coaches usually carry a warranty; one-off conversions rarely do. RVIA membership is a useful standards signal (rvia.org).
9. Tyre DOT dates — the four-digit code on the sidewall tells you the week and year of manufacture.

Is a small motorhome right for you?

A small motorhome suits you if: you move campsites every few days, want to drive the rig yourself without anxiety, value trailhead and park access over square footage, need it to double as a second vehicle, or want to store it at home.

Look elsewhere if: you park in one place for a week at a time, travel with more than four people, need a separate dry shower and toilet, or want a residential-size fridge and oven. In those cases a travel trailer gives far more room per dollar, and you keep your tow vehicle for day trips.

When you are ready, the full inventory of small motorhomes and camper vans for sale from verified US dealers is one click away, and you can filter by make, drivetrain and budget on the main listings page. If you need an interior shower as a hard requirement, jump straight to vans with interior shower.

Frequently asked questions

What is the smallest motorhome you can buy?

The smallest true motorhomes are around 17 ft — short-wheelbase van conversions on the ProMaster 136″ or Transit 130″ chassis. They sleep two, carry 10–20 gallons of fresh water, and usually use a cassette or portable toilet rather than a full black tank. Below that length you are looking at a camper shell or a micro travel trailer rather than a self-contained motorhome.

Are small motorhomes worth it?

Yes if you travel often, drive the rig yourself and value access over floor space. A small motorhome doubles as a daily vehicle, which no large coach does, and it opens campgrounds that turn big rigs away. If you camp in one place for weeks at a time, a travel trailer gives more room per dollar.

How many miles is too many on a used small motorhome?

On a diesel Sprinter, 150,000 well-serviced miles is normal and the drivetrain regularly passes 300,000. On a gas chassis, buyers get cautious past 120,000. Service records matter more than the odometer — the RV systems usually fail long before the engine does.

Do small motorhome campers need a special licence?

No. In every US state a Class B or small Class C under 26,000 lb GVWR can be driven on a standard licence. Check your state DMV if you plan to tow a trailer behind it, since combined weight rules differ.

What fuel economy do small motorhomes get?

Typically 14–22 MPG. Diesel Sprinters sit at the top of that range on the highway, gas Transits and ProMasters in the middle, and AWD versions of either lose 1–2 MPG. Roof racks, awnings and heavy builds all cost real economy.

Can you live full time in a small motorhome?

Many people do. The practical minimum spec for full-timing is an interior bathroom, a real heating source, at least 6 kWh of battery, 300W+ of solar and 25 gallons of fresh water. Below that you will be tied to campgrounds and paying for hookups.

How long do small motorhomes last?

The chassis commonly reaches 250,000–300,000 miles with maintenance. The conversion needs attention sooner: roof sealant every 3–5 years, lithium batteries at 7–10 years, and water pumps, fridges and fans somewhere in between. A 15-year-old small motorhome with a well-maintained interior is a reasonable buy; one with deferred maintenance is not.
