I have a new Jayco 5th wheel and we discovered that the tub leaks. It seems like some caulk would fix this. My question is should I take it back to let dealer do it or just do myself? Also a rather dumb question but I have been seeing these globe like beaded looking string lights that look like beaded lamp shades. I would love to find these so if anyone has a clue what I am talking about please let me know where I could get these. Thanks
