Pick the Fleetwood Altitude 31W if…
Pick the Fleetwood Altitude 31W if you're a couple or couple-plus-one who wants the full-length Class C floor with single slide, residential fridge, theater seating, factory generator, and 50-amp service. The 32.5 ft body and electrical package handle two roof ACs and full residential loads, and the slide gives proper lounge space. Best fit: a couple full-timing or doing extended trips who prioritizes floor size and electrical capacity over a higher sleep count, and who values the $1,965 savings.
Pick the Winnebago Minnie Winnie 25B if…
Pick the Winnebago Minnie Winnie 25B if you need to sleep 6 with a bunkhouse for kids in a shorter, more nimble Class C. The 26.33 ft length fits standard pull-through sites the Altitude can't, the bunkhouse covers kid sleeping, and the 18-gal LP runs your furnace longer in cold weather. Best fit: a family of 2 adults plus 3-4 kids who needs the bunk layout above all else, prefers easier driving dynamics, and is comfortable paying the $1,965 premium for the family configuration.
