Just got sent this link by a friend. I just bought a house with an 8' door so I can drive inside with the tent on (that was a requirement for any house I got). I was planning on building something to store the tent, but this is practically exactly what I was looking for anyway!
Figured a few people here might want the same thing.
*edit, and for those who can't see the facebook post, here is the amazon link! https://www.amazon.com/dp/B0009I8AO6/ref=cm_sw_r_cp_apap_WMUcd1BDsfqBC
I use one of these for my hitch box and it has served me well
