I tow a 3160 with an old 2000 F350, yes I have airbags but I really installed the airbags for when I was hauling a 990 Arctic Fox Camper. Airbags will level out the truck similar to adding a leaf in your spring pack etc. Biggest thing in my opinion is calculate your weight or better yet if you have a hitch hook up and go across a scale to get actual weights, and make sure that your tires are rated for the weight you will be carrying.
