Welcome, fellow UHauler! You've gotten yourself a dandy - probably the lowest maintenance, strongest-built FGRV anywhere. We put 20,000 miles coat-to-coast on ours the first two years we had it (this year not so much - too busy with urgent matters).
website linked above is valuable, but I had a poor experience dealing with the webmaster and recommend caveat emptor
. The manuals he sells are worthwhile, though.
Happy trails to you!
