Pick the Fleetwood Altitude 29H if…
Pick the 2027 Fleetwood Altitude 29H if you want the bigger Class C floor on the Ford E-450 platform with a factory 4,000W generator, residential fridge, theater seating, 50-amp service, and the 2027 cosmetic refresh. The slide and 32.5 ft body deliver true couple-friendly full-time accommodations. Best fit: a couple or empty-nester pair planning multi-week or full-time use, who values the longer floor and electrical capacity over sleep count, and treats the 2027 update as worth banking the $1,965 savings.
Pick the Winnebago Spirit 25B if…
Pick the 2026 Winnebago Spirit 25B if you need to sleep 6 with a Class C bunkhouse and prefer a shorter, more manageable body. The 26.33 ft length keeps you inside standard pull-through campsite footprints, the bunkhouse covers kid sleeping, and the larger 18-gal LP extends cold-weather operation. Best fit: a family with kids who needs the bunk capacity, prefers easier driving dynamics, and is willing to pay the $1,965 premium for the family-focused configuration.
