Welcome to our forum.
We just took a 2000 Grandee in on trade with leaking glue joints. I haven't had a chance to take a look at it yet, but apparently a competitor of ours had it back at their shop for repairs for a couple months and either never made the effort to fix it or couldn't fix it.
I guess the bigger concern here at this point is...Have they found what the problem was and fixed it? What was it and what did they do?
