We purchased an RPOD 180 4 months ago and absolutely love it...
Following is our list of recomendations.. Some of which we have already installed.
A push pull battery disconnect installed inside the unit.. Saves on battery drain when not in use. TV hooked up to the inverter. DC outlets. TV sound hooked up to the speaker system. A cabinet installed over the bed and above the windows. Self leveling jacks.

There needs to be something done to the jack on the trailer hitch. If the trailer is parked on uneven ground the jack either does not go high enough or low enough. A couple of the drawers could be deeper, which would make more space. And a small fan installed in the bathroom to push moisture out.
