Well we picked up new 345RF a week and a half ago and we have already made several mods. Inside we added a 24 led tv mounted on the bedroom wall, key hooks in the closet by the door, and bathroom accessories. Outside we have done e few more things like gas hatch lifts on the front cargo door so it doesn't shut on my head, a big bubble level on the front, screen covers on the furnace inlet and outlet, rubber bumpers on the bedroom slide out corners so I don't hurt my head, and JT Strong Arm stabilizers. In the near future I am going to install a Max Air vent cover on the bathroom vent and a Wingman on the antenna. Also, forgot that i put the foil bubble insulation on all the bedroom windows so it is dark in there. We are really happy with the quality of the unit so far. The only problem we have had is the sink dripped a little where the brackets hold it to the countertop, nothing a little caulk won't fix.
