These are $500 new. GUC, we just upgraded to a tent trailer. This will fit a queen-sized mattress with lots of room for gear no problem. We had that plus a small table and chairs in there. No issues with rain or weather. *There's a loose screw in the one of the mechanisms in the top but it's never impeded the setup nor structural integrity. I believe it's fallen out before and I just put another screw in.
