[Help, my slideout extends while driving.]

I also have a 2008 Discovery 40X. I had the same problem with my coach. The dealer found that the wiring harness for

that slide had an abrasion and was preventing the slide lock from engaging. They repaired the abrasion and rerouted the wires to prevent future problems. They also did the same for the other slide. Problem fixed!
