I have the littlest Ford Explorer, the 2-door Sport. (I sort of inherited it from my partner's sister - it's a long story.) I sometimes have to buy new steel which usually comes in 20' lengths, which don't fit in my little vehicle. One thing about my car is it has 2" trailer hitches both fore and aft. I'm thinking of making a little roof-high rack at each end that I can clamp long stock on - never too much, maybe max. 200 pounds. Here is a commercial canoe rack that is the same idea, although my design will differ:
