Congrats, Judy and don't worry because the vehicle has a lot of bang for the buck.
Click on the spy glass (search feature) and type in various subjects with regard to "lists" that spell out what to look for when taking possession of a new RV.
Also ask any specific questions in the "Beginning RVing" thread that have perplexed.
And above all, don't let the dealer rush you into signing off on the RV dealer's final punch list. If you aren't satisfied or if they're trying to give you the bum's rush before you've checked everything out, just walk away and see how quickly their attitude changes..
You might even rent a similar unit before you get the new one—to see how the various elements of a typical unit work. You'll understand the walkthrough with more awareness.
