Beercan,
Congratulations on the purchase of your new RV. Members who own that specific model may offer you some "unit specific" comments regarding what to look for that isn't on any other RV, but if you go to the Keystone Questions section of this forum, the very first item you'll see is the PDI (pre delivery inspection) checklist. Download that checklist, study it and take it with you when you inspect your new RV. It will guide you through the many systems in the RV and help you with not forgetting or overlooking items that you should be inspecting. Keep in mind that the PDI is really the only chance you and the selling dealer will have to go through your RV from top to bottom, front to back together. Use this time to make sure that everything is up to your standards BEFORE you sign on the dotted line. After you do, then it's going to be tougher to get the dealer to take care of things on "your RV" rather than fix things on "his RV" so you'll buy it.
Also,
to the forum, we're glad you joined and look forward to hearing from you as you learn to use your RV and to modify it to make it your very own.
