Rig Selection
Choosing Your Full-Time RV: Class A, B, C, or Fifth Wheel?
Pros and cons of each RV type for long-term living — the practical breakdown for full-timers, not weekenders.
14 min read
The RV that's perfect for a weekend camping trip is often wrong for full-time living. Full-timers evaluate rigs on different criteria: livability over months, not days; storage for everything you own; build quality that holds up under 20,000+ miles per year; and amenities that make sense when the RV is your only home.
This guide covers each major RV type through the lens of someone who will live in it every day. Skip the marketing copy — here's what actually matters.
The Van
Class B RVs (camper vans — typically a Ford Transit, Mercedes Sprinter, or Ram ProMaster base) are the smallest full-time option. They're popular because they're easy to drive, park in normal spots, and get better fuel economy than larger rigs. For the right person, they're genuinely enough.
Pros for Full-Timers
- ✓ Parks in normal parking lots and city garages
- ✓ Much better fuel economy (15–20 mpg)
- ✓ Easier to drive than large rigs — less mental load
- ✓ No tow vehicle complexity
- ✓ Lower insurance costs
- ✓ Easier to stealth camp in urban areas
Cons for Full-Timers
- – Extremely limited storage — no room for hobbies
- – Kitchen is minimal — serious cooking is difficult
- – No slide-outs — bathroom, living, sleeping all same space
- – Couples can strain the relationship
- – No desk/office space without major setup each time
- – $100,000+ for quality new vans (Thor, Airstream)
The Mid-Size Motorhome
Class C motorhomes (22–38 feet, built on a truck cab chassis) are the most popular entry point for new full-timers. They balance livability with driveability — more space than a van, easier to handle than a 40-foot Class A. The distinctive over-cab bunk area is a Class C identifier and adds usable space above the cab.
Pros for Full-Timers
- ✓ Reasonable learning curve for new drivers
- ✓ More livable than a van — actual bedroom, kitchen
- ✓ Tow car capacity for most models
- ✓ Mid-range price ($60,000–150,000 used)
- ✓ Good slide-out options expand living space
- ✓ Easier to find service than larger Class A
Cons for Full-Timers
- – Less storage than fifth wheels of similar length
- – Lower-end build quality common in entry models
- – Limited tank capacity requires more frequent dump/fill
- – Fuel economy worse than Class B (8–12 mpg)
- – Bedroom less private than slide-out fifth wheel designs
The Full-Size Motorhome
Class A motorhomes (32–45 feet, bus-style body) are the largest motorhomes and the most comfortable for long-term living. When well-specified, a Class A feels like a genuine home — real kitchen counters, residential-style bathrooms, dedicated office space, and serious storage. The trade-off is everything else.
Pros for Full-Timers
- ✓ Maximum living space for a motorhome
- ✓ Residential amenities: real appliances, full bathrooms
- ✓ Diesel pushers are mechanically durable for high miles
- ✓ Tow car capacity is essentially mandatory (and manageable)
- ✓ Best HVAC systems in the motorhome category
- ✓ Multiple slide-outs create excellent open floor plans
Cons for Full-Timers
- – Significant driving complexity — 45 feet of rig
- – Fuel: diesel pushers get 7–10 mpg, gas worse
- – Premium purchase price ($150,000–500,000+)
- – Can't access smaller campgrounds and tight roads
- – Repairs are expensive — specialized diesel techs required
- – Some national park roads have length restrictions
The Towable King
Fifth wheels are the most popular choice among full-timers who already own (or are willing to buy) a capable pickup truck. The coupling mechanism — a kingpin that attaches to a hitch in the truck bed — is more stable than a travel trailer's ball hitch, and the raised front section creates a bi-level floor plan with a bedroom loft that separates living and sleeping areas far better than any motorhome of comparable length.
Pros for Full-Timers
- ✓ Best square footage per dollar of any RV type
- ✓ Bedroom loft creates genuine separation of living areas
- ✓ Truck is independently usable — errands without breaking camp
- ✓ Superior build quality at the same price point vs. motorhomes
- ✓ Larger fresh water, gray, and black tanks than motorhomes
- ✓ Easier to repair than motorhomes — fewer engine complications
Cons for Full-Timers
- – Requires a heavy-duty pickup truck (adds significant cost)
- – Combined rig length can exceed 65 feet
- – Backup and maneuvering has a learning curve
- – Truck bed not usable for cargo (hitch takes the space)
- – More height clearance requirements than Class A
How to Decide
Do you have (or want) a pickup truck?
Yes → seriously consider a fifth wheel. No → motorhome (Class C to start, Class A when experienced).
Are you solo or a couple?
Solo → Class B or smaller Class C may be genuinely enough. Couple → at least a Class C with slide-out or a fifth wheel.
How important is urban access?
Cities matter → Class B or Class C under 30 feet. Open road/nature focus → size up for comfort.
What's your mechanical comfort level?
Comfortable wrenching → used diesel is great value. Not mechanically inclined → budget for warranty/shop costs.
New or used?
Used (3–7 years old) is almost always better value. The original owner absorbed the depreciation; you get most of the useful life.
