I ran into the exact same problem the OP is suggesting with a dealer here in Akron Ohio that I won't mention.
They had mine for 3 months and didn't fix about 19 things on a list of 22 while still under warranty.
They had it again for 2 weeks and still failed to repair ANYTHING and damaged my coach all the while trying to say "I must have rubbed against a tree....
(Caught them in that lie)
I ended up complaining enough that Keystone sent 2 reps to my home to see what the issues were; and at that time they scheduled service at the factory for me. ALL 3 years out of warranty.
That said; if you fail to get the service you require from your local dealer;try calling the Mfg. Keep detailed information of all your communications and phone calls of who, when and where you talked to some one trying to resolve your warranty issues.
And make some noise on a forum detailing who it is that's not providing what should
be provided to you...go on all the forums you can....they don't like their names put out there for people to see when they mess up.
The squeaky wheel gets oiled first.
