I have these two items, not hitch, but tire carrier...Havent used yet so i couldnt tell you how well they work, but they are 119.95 and 139.95 dollars, respectively. I got them from Gemini-sales.com, and the brand is Swagman.
I've seen a hardtop Tent for the new JK in some SEMA pictures...Pretty sure its by American Expedition Vehicles. They are in the process of updating their site so i couldn't find any pics unless i went back through the thousands of sites/pictures from sema i've looked at.
To be honest, i would rather just pitch a tent on the ground, I would hate to buy a new, obviously expensive, hard top to camp on my jeep :lol: I dont think it would save me enough time or effort.
A question i have, do most TJ roof racks pivot back so you can drop the soft top without completly taking the rack/frame off?
