I am thinking of putting on air bags to help level the truck when towing. I checked a while back and was told that you could not get airbags with a B&W turnover ball. Does anyone have airbags with this hitch. If so can you still use the turnover function, or does the airbag block the release under the fender. What did you pay for your set up? I can't decide if an on board compressor would be worth it or not. The only brand I have seen is Firestone, any others anyone recomends? Thanks for the insite, Levi
