I have a 1.25" -> 2" receiver adapter, which I used with my Mercury. It does stick out quite a bit, as the adapter adds about 4 inchesI wasn't looking at this route for two reasons. I don't really want to put a receiver on the car, and the rack on the suburban is a Thule T2, which only fits 2" recievers. If there is a good way to adapt this rack I would certainly consider this option but it seemed like a messy setup. I also have the roof rack from a previous car, so cost is actually in favor of the roof rack where I would just have to buy the proper fit kit.
