Things you would like to see on a trailer

I've been looking at smaller (under 20ft) trailers for a while:

More layout options
Oven standard
Make "conveniences" optional - things like tvs, microwaves and other 120v items

I like the idea of the moonroof - a clipper owner took out his cabover escape hatch, expanded the opening and installed a truck nose cone over the cabover bed. Really opened things up!
