Here are some of the initial mods:
Added a velcro strap to keep the bedroom door from swinging into the way constantly.
removal of bracket below wondow curtains. With the plastic l bracket gone, we can actually rest our arms on the backs of the cushions when sitting in the dinette.
Added a door holder and removed the stock door shock so the door opens all the way now.
added carpet steps so the dog won't kill herself when going in and out. Threw away the springs and tied securley with sailing rope.
dual battery boxes, screwed to frame, handles cut off on one side each so they fit exactly, then zip tied the cables and used the straps just in case.
Added a battery disconnect. also added the 'hot' wire so the emergency brakes will still work in the switch is in the off position when towing.
moved the spare over and added a Curt reciever hitch for the bike rack. 350lb tongue weight, 3500 towing...so we should be good.
Still need to add invertor for a TV and an extra water tank under the front bed. We like to boondock most of the time and the wife likes to fall asleep to a TV and then have it automatically turn off w/o running generator.
