Romer, I remember reading your write-up over on Mud a short time back.
You know, and I saw someone else mention it too over there, I do not see why the Cabela's deluxe tent cot could not be made to work on a roof rack.
Plus you can store it in the rig.

That is if it is worth the trouble to mount it up there.
Depends if you want to be a foot off the ground, or higher up.
I almost bought one of these, and it would have been way cheaper than the route I took.
However space is tight enough in my rig now, and I like the idea of the tent on the roof.
Eventually it is going to go on
one of these when I move and get a garage.
