The only thing you have to be careful about is the weight rating of various racks. I was looking into the Yakima models when I first started but was disappointed that they were rated at only 250 lbs.
That is how I got to the Surco Safari rack (along with some great help from Roadie) which is rated at 350 lbs. As I was planning for a tire, 2 gas cans, 1 water can, camping equipment, and a hi-lift jack at the time, I definitely needed the higher weight rating.
Now I'm no expert on roof top tents, but due to the weight requirements don't they usually mount straight to the vehicle's roof hardware?
