Picked up my new 2100 at the factory in October, 2012. Since I live 1,200+ mile away, had inquired about repairs done locally. As others have said, you let the factory know the problems, find a good shop, pay the shop, send the bill to PC, and they reimburse for any warranty/construction problems that were repaired.
I went to Camping World in Denver. I had very few, very minor problems all of which were fixed and have had no problems since.
