10x, Congratulations. Just make sure the dealer shows you how and that everything works. Have them hook up water and check under all the sinks for leaks. Run all the systems that will on 12v, and then the 120v. Run the propane. I my case they did not have fuel for the generator, so I did not know if it worked until I put some fuel in the tank.
Don't forget to check the little things as an example. Does dinette table fit between benches, ours did not. Do the legs hold the table without excessive wobble, ours did not. Do all the window shades and locks work properly. We found out after leaving that ours did not. No big deals but, Hey If I had found the problems at the dealer I would not have to fix them on my own later. ( My dealer is just to far away for little things)
I have looked at several check lists on FRF you should be able to find them doing a search. Hope this helps.
