Bob,
Most, if not all the problems you decribe would have been covered by the TM warranty and your dealer would have repaired them at no cost to you.
We too, had a few of the type problems you mentioned. I gave our dealer a list of 13 problems more than a year after we bought our new trailer, and they repaired all of them without cost to me, although I thought I'd be paying for some of the repairs.
I am handy with repairs, as you are, but I figure since the dealer was willing to support the unit beyond the legal terms of the warranty, why not let them to it. Our dealer support was superb!
