I installed the TM-2025RV to the right of the Power Distribution Panel, between the panel cover and the side wall. It sits at a slight angle because of the trim strip on the wall, but I did not want to cut and remove the strip. It is easily visible.
I ran a new 12V DC line from the Power Distribution Panel, and put the Remote on it's own fuse. There were three (now two) vacant fuse locations on the PDP. I may remount the switches through the wall to tidy things up a bit. The rear remote gets it's power from the 12V circuit that powers...
Installed a Dirt Devil 950 Central Vacuum System, with the inlet at the steps leading to the bath/bedroom. That way the 30' hose will reach anywhere in the RV.
