Thanks everyone! It's good to know that this general floorplan works. It's one of our favorites so far. Camplite has a similar model as well.
Soundguy is correct in that we usually are in some sort of campground with facilities (although water is becoming less reliable in some of the public campgrounds). If we were to boondock for any length of time (instead of just overnight on the way somewhere), we could tote extra water in the back of the TV, but we're pretty good at conserving water. We have a slide-in camper with around 35 gallons fresh water and a portapotty. We don't have problems with THOSE tanks. Our 7 gallon gray tank is annoying though. Obviously we don't shower into it!
The hybrids are really appealing but the 7-foot wide ones (and we ARE limiting ourselves to around 7 feet) are targeted to low budgets and low weight. I should have looked at them beFORE looking at the Winnebagos and Lances because then I might not have been so turned off by their craftsmanship. :) But on the other hand, I could lose several feet in length with a hybrid. Hmm.
The Micro Minnie and Camplites are the rare 7 ft trailers that pack in all the nice options and better workmanship.
