Congratulations on the upcoming Pinnacle! I'm sure others will chime in with their experiences, but those "plans" are a significant money maker for the dealer, and cost thousands of dollars. Your new rig comes with a warranty, and if you're handy, you can take care of most other issues yourself, saving a lot of money. We were given a free year of Route 66 when we bought our TT, and never used it. On the same note we did switch from AAA to Good Sam Roadside Assistance after the year was up, but haven't used that one yet either. That was 8 years ago.
I don't have any knowledge on the appearance plans, so I can't comment further on those.
If you're considering them, look at the cost, and read ALL the fine print FIRST.
Every day's a learning experience, though sometimes not what we expected.
