I have a 2002 Shasta and I have had not leaks to speak of. I had a pressure test done a few months back and got some spots repaired. After talking with the guy at the shop, he convinced me to recaulk the entire motorhome.
So now I doing a section at a time, removing old caulk with a razor and cleaning it before recaulking. He suggested using auto pinstriping tape to get professional look seams. Seems to be going so good so far. A lot of work and time and only have a 1/3 of the unit done. But it is something I can do and I am ensuring quality control.
