I recently got a brand new 13 foot Scamp and just looove it! But there's a few things I wish I'd known. Here they are for your benefit:

It takes 2 or 3 days to get the rather unpleasant "new Scamp" smell out. Be prepared to keep the windows and the fan open for a while.

These things are complicated! And the manual / instructions are poor. I had never used an RV before, so I needed to learn how everything works (water, electrical, heat, etc). Most of the videos I found did not apply to my particular setup. If I did it again, I would find a veteran RV owner willing to camp with me who could explain how everything works. They do give you a rundown of everything when you pick up your Scamp, but they go over everything so quickly, it is not enough.
