Hey, my tepee outdoor is leaking badly at the rear lights section. Water is pooling adjacent to the lights in the plastic ledge that sits above the wheel arch. Its been to the garage twice, they have added a small bead of silicone to seal, but still water is getting in. Anyone had a similar situation? Its a 2014 model, Ive had it over a year with no water issues, then all of a sudden its pouring in each side. The garage i use is very good and they were stumped. I want to insulate and ply line the back to use as an occasional camper, so the 'solution' of drilling holes to let the water out is not preferable. Any advice greatly received!
