The remote is a Lippert product. I found a single pc board in the compartment with the landing gear that seems to be the whole thing. All the power lines for the slides, landing gear, and awning terminate on the board, and there is a little antenna hanging off it. All of the circuitry is potted in some kind of gel material.
Since the whole thing seems to be a single board, it should be relatively easy to install. The toughest part would probably be locating and rerouting or extending all the power wires for the various slides, etc.
The system is listed in the Lippert catalog. They also offer some other remote controlled stuff like leveling systems.
