Just some thoughts that may explain some of the questions you have:

1. The overhead light switches are usually on an inside wall or in an overhead cabinet because the outer walls are vacuum formed with rigid foam in them, To cut out a box to mount the switches could lead to condensation problems and should a wire go bad, there's no way to repair it without destroying some of the foam in the wall. So for future "ease of maintenance" usually there's no electrical connections in the walls if it can be avoided. That's one of the reasons many RV kitchens have outlets mounted under the cabinets rather than along the countertop.

2. Beats me why no A/C vents in the bedroom. I haven't been inside any RV's with ducted air that don't have vents in the bedroom. You might want to check another "same model" as yours and verify that there aren't vents in it either.... Hmmmmm

3. The main door on our Cougar also has a gas strut that holds the door open at a 90* angle. It won't open fully against the RV wall because the awning rails are in the way. On some RV's the furnace or hot water heater may be installed behind where the door would open. Check your RV to see if there is anything that would prevent you from installing an entry door holder. If there's nothing in the way, you can buy the hardware from almost any RV dealer's parts department. Installation is relatively easy, just make sure you have some kind of "framework" behind where you mount it so it's not supported by the fiberglass/aluminum siding only. That's a sure fire way to have a few extra holes in your trailer, the first time someone pulls on the door and the holder doesn't break first.

Hope these comments may help you understand a bit better.

Good Luck.
