I love 4x4 suburbans. Yours looks great. I sold a pair of suburbans a couple year ago, one 4x4, and one 2wd. I sure miss all that interior room. I hope to own one in the future. I found this nice original 1972 on Evil bay If I had the cash I would already be on a plane and beating his door down to get it.
