You can go to
www.rvtrader.com and search for similar units. It looks like a reasonable price.
It's a fairly common floorplan and we had a similar one. It's like having your own motel room with a kitchen. It's a lightweight rig partly because it doesn't have a slideout.
We liked ours because we don't spend a lot of time in the rig itself. As long as you don't see signs of water leaks, it should be fine.
You might want to check to see about reservations where you want to camp. Summer weekend reservations can be difficult to get.
Good luck and welcome to the forum!
