I recently purchased a 1997 Chalet 2000 series 15.5 foot A-frame. When it is driven in heavy rain, water leaks into it. I believe there is supposed to be a rubber cover over the hinge, but that is missing. The former owner used roof sealing caulk to coat the hinge, but this caulk cracks and is not effective. I would appreciate suggestions as to how to cover or seal both the front and back hinge effectively without spending a mint or having to disassemble the roof and sidewall .
