Redoct62,

to the Keystone RV Forum and to the Keystone RV family. I'm sure you are as excited about the new RV as your sons are. There is a lot of difference in today's new RV's and the ones that were built even 5 years ago.
There is a pre-delivery inspection checklist (PDI) posted on the forum. Click on this link and it will take you to the location where you can download the checklist.

It's a very comprehensive guide to follow on that initial inspection and orientation with your dealer. Take some time to look it over, then carry it with you when you go to pick up your new RV. Make sure the dealer goes through your new RV and shows you how to use and operate everything. Make sure all the systems are functional and work properly.
The PDI checklist will help you in remembering to check everything, even some things that you can't see.
Again, welcome and enjoy your time on the forum as well as your time in your new rig.
