Well ... the 25B has 2 permanent beds in it ... one in the back and one over the cab. One person in each makes for a lot of room for each person.
My wife has a bad back, so in our 24 ft. Itasca Class C she gets the corner bed all to herself to sprawl out in. I use the overhead cab bed to sprawl out in. My wife uses a stool to help crawl up onto the corner bed, which is the same stool that she uses for an easier reach into the high cabinets, so the stool serves a dual purpose.
The chassis under our 24 footer is the E450, so we can load it up as we wish with no concern for any over-loading or negative impacts on handling while going down the road. The wide rear stance of the E450's dual tire sets provides for great lateral stability on curves and in high cross-winds.
