I am not wild about the aluminum floor. There is a metal strip, about an inch wide, riveted over each of the joints, so the floor is not smooth. It sags a bit between the joints. It is "bouncy" and is cold during cold weather camping (which I don't do a lot of).
The other problem is lack of storage space. We solved this by removing the inoperable suburban furnace and associated metal ducting. This freed up loads of storage space under the sink and oven. I kept the outside furnace vent piece, which I backed with a piece of black painted aluminum, so there wouldn't be an ugly patch (so on the outside, it still looks like we have a furnace).
For heat, I installed an Olympian Catalytic heater on the side of the oven cabinet (by the door). So far this has worked well.
We tried a low cost prego-like flooring, but the metal floor "sweated" when it was cooler than the trailer air and mildew formed between it and the plastic vapor barrier that the flooring requires. We had to rip it out and replace it with carpet.
What we really like is the openness. Our model has both front and side gauchos. Three full sized side street side windows and the wrap around front windows really go a long way to make the trailer look like it is a lot larger than it really is.
I neglected to mention above that another weight savings in the trailer is that all the side windows are lexan, not glass. The front flat and wrap around windows and the rear window are glass.
Here are some photos. They were taken at last years International, so the windows are covered with reflective foil we bought at Camping World to help keep the heat out....
