I missed the "Minnie Winnie" part of your title. Went and looked the coach up. I like the floorplan. I like the dinette AND sofa which is rare in a smaller unit. As long as the 54" wide bed is wide enough for you! We have the 60*75 which is queen width but shortened. I think 54*80 is standard "double/full" but with a corner cut off. You should still be able to use standard sheets which is a big plus.
Our first C had Cabover sleeping only. Well, a very punishing sofa that we never used. It was 24' and we would have kept it if it had any "bed down" layout but we'd decided we were too old to be climbing into "the loft" at night.
What I wanted to see was the Wheelbase. Crunching numbers, your WB is 57% of total length and that is a good thing. You should find it comfortable to drive and that it tracks well on the road. If it doesn't it should be easily fixable.
As you get closer, look up Michelin's Load-to-Pressure table and have it with you. Take a test drive that includes a truck stop and weigh the coach on their CAT scale for $10. Then adjust tire pressures to what the chart says based on the CAT weights. Now do your drive. It should behave about like it will after you buy one, but you'll want to do that again after you load people, equipment and supplies for travel.
Looks good, and Winnebago is an above average brand. 25B only offered on Ford E350 which is a rock solid chassis.
