Pick the Fleetwood Altitude 27U if…
Pick the Fleetwood Altitude 27U if you want a Class C with the outdoor kitchen, fireplace, factory 4,000W generator, residential fridge, and 50-amp service on the Ford E-450 platform.

Pick the Winnebago Spirit 22M if…
Pick the Winnebago Spirit 22M if you want a more nimble Class C body that sleeps 5 with bigger grey and black tanks at a lower price. The 24.42 ft length parks in standard pull-throughs, the 45-gal grey and 40-gal black tanks support multi-day boondock stays, and the 18-gal LP extends cold-weather operation. Best fit: a family of 4-5 who prefers the easier driving dynamics, prioritizes the bigger tanks for off-grid stays, and prefers to save $4,984 over the Altitude's feature density.
