The original design included a slanted roof (to help cut down on drag when moving it),a loft for sleeping space, and a small porch on the end. Wendy and I were both happy with the design, although there was some concern about staying street legal with the height while still having a decent sized sleeping area.
Getting rid of the loft also opens up the kitchen and bathroom quite a bit. No more 6'3" ceilings. Now the kitchen and bathroom will have 7'6" ceilings and the living space, 9'6"
Our couch, which normally will sit flush against the platform where the kitchen and bathroom are, is attached to a platform (with storage, duh) that houses our full size mattress. The couch opens up and will be a hidden litter box.
The small stair case that leads from the kitchen to the living space also pulls out to reveal more cubicle type storage
This is a very similar design on a bit of a smaller trailer, but the deck will be built like this and will have an awning similar in nature. This house's deck actually folds up against the side of the house for travel. It means a bigger deck and protection of our door whenever we do travel
