I have a high quality tent made by 1 of the top tent companies that is a real attach to the hatch tent. I originally got it for a mini-van years ago and it is a great way 2go. It attaches completely to the rear opening ant tightens with a draw strap setup. It has a deep well to step out of the vehicle and into an ante-chamber for the tent (airlock

) and a zip door on the tent for privacy. Worked great for seperating the kids from the parents.
I will try to check it out and get the name.
