Just picked up a well used class c lazy daze. last owner had it sitting in a storage yard for several years, so it's got a few issues. I've had a travel trailer for several years, so I know the basics...
thanks John, I'm thinking it might have something to do with the tow system. there's what looks like an air chuck sticking out the back next to the trailer hitch, but no big electrical plug, (just the 4 pin) I know the previous owner towed a car at some point.
