First, calm down and then learn to proof read your posts. As I see it, your coach will not be built for another one thousand years. Try to give better info too. What papers did you sign? A purchase agreement or actual purchase documents. Who determined a brand new generator built by Onan company, not Jayco, needs a new starter. The cab A/C is same thing, built by another company rather than Jayco. Fridge will need 24 hours minimum to cool. Do you know when it was turned on?
After the walk thru, called the PDI (pre delivery inspection) in our circles, did you sign any more papers? If you did, you own it. If not, run, don't walk, away from that dealership as fast as you can.
The problem I am having with your post is this is a lot of different systems to have issues in a new coach. Just doesn't sit right.
