Cabinfever, Congratulation on the new RV and welcome to the forum. As for your quesiton regarding a walk through with the dealer. There is what's called a "pre-delivery inspection" where the dealer goes through and gets everything ready for delivery, then in the second phase, he walks you through, shows you how everything works, answers questions and explains anything you may not understand. During that introduction to the trailer is when you have the opportunity to examine, ask questions, make sure that the RV meets your satisfaction. Anything that needs to be repaired, added or adjusted, etc should be done BEFORE you sign on the dotted line.
There is a predelivery checklist available on this forum to help you with this walkthrough. You can find it in the Keystone Questions section. It's the first item you'll see in that section. The URL is:
