Rapid Camp Caution!! I found out where our receiver is located the hard way after slides and awnings would not work in our 2015 Challenger 37TB. After a call to Thor support and 3 hours of crawling around in the nooks and crannies, I finally took the inner wall in our master bed well underneath the mattress Low and behold I found the multi-function board and relay for the Rapid Camp system. You can read the trials and tribulations I enjoyed in my post http://www.thorforums.com/forums/f8/...king-5353.html
Not only does the Rapid Camp system add remote control; it also adds the safety feature of locking out the overhead bunk, awning use and slides with the motor switch key turned on. That is what the purpose of the relay just before the multi-function board. If the relay is fried - the aforementioned will not operate.
