About Class B
Class B is the RIA / RVIA-classified motorhome on a van chassis (Sprinter, Transit, or ProMaster underneath). The difference from a 'conversion van' is that Class B is built and sold by an RV manufacturer (Winnebago, Coachmen, Roadtrek, Pleasure-Way) with the entire interior systems integrated and certified. Walks the line between van and small motorhome.

Stand-up context
Most Class B: 6'1-6'4" stand-up via extended pop-up or high roof.
Power system context
Integrated electrical: 200-400 amp-hour lithium house, 200-600W solar (varies by brand), inverter, propane or diesel heat. Class B has bathroom (typically wet-bath) — full motorhome amenity, smaller form factor.
When Class B wins
Trips where you want full motorhome amenities (bathroom, kitchen, climate) in the smallest motorhome possible. Couples + small families. Trips that mix on-grid + off-grid (Class B does both well).
When Class B loses
Pure boondocking trips with no need for bathroom + cassette toilet (a stripped conversion van costs less). Trips with 5+ people (Class B is too small for groups).
What official guides don't tell you
PickRV — first-hand context.
Class B brand differences matter — Winnebago Travato is gas + Onan generator standard; Storyteller Overland MODE uses diesel + alternator-charging. Match brand to trip profile.
Wet-bath (toilet + shower combined) is normal in Class B — takes adjustment for first-time renters used to dry-bath in larger RVs.
Class B is NHTSA-classified as motorhome — drives under standard Class D license in every state. Insurance treats it as motorhome, not van.
Resale value on Class B is highest in the RV market — popularity is driving prices up.
Some Class B models have factory rooftop tents available — sleeps 2 more above the cabin.
