Congrats on the new unit! We have had ours for just about a year now, and we love it. It looks massive in the driveway, but tows like a dream, and still isn't the biggest unit in the campgrounds. Buying a used one was smart on your part; someone else worked out all the bugs, but it's still "young" enough to provide you years of enjoyment.
If I had to do it over again, I maybe would change a few of the options I got, but I would not pick another unit. I have seen nothing in the campgrounds or at the shows that I like better. Good luck with the new unit!
