Good luck! Consider taking a lot of pictures because when you get home, and if you haven't purchased it, you will do a lot of talking and may want to refer to pics to answer questions, etc. Take your time when looking and look at every square inch you can....especially for flaws and sloppy assembly. Sit on the seats/furniture long enough to really understand the comfort level. Check the mattress....I would assume that I would be replacing it because we've seen few stock RV mattresses that we would keep.
Have fun!
