Yes most times it's a ground issue. Like working on a Corvette or other fiberglass body rig. You can't just ground to the body or frame. So for some reason there always seems to be more ground problems with these types of rigs.
Oh shit that makes sense that's a good point. Like the jeep taillights just ground through the mounting screws through the tub. Not that easy in this thing... the wire goes all the way to the driver side front of the camper where it plugs in. Awesome!! Thank you hopefully that is all it is
