I have the same issue with a short somewhere in the wires to the aft slideout awning LED lights. It is an intermittent problem which comes and goes sometimes with slideout in and sometimes slideout out. Not always tripping immediately. There is obviously a ground in wiring affected by movement of the slideout. It burns out the 15 amp fuse in panel. Dealer had apparently fixed it for a short time, but now problem has returned after warranty expired. This conductor pair runs up through top of slideout and is very difficult to access.
