cyclone ,nice setup, especially for lunching a v-drive at very shallow angled ramps.I had airbags way back on my 66 CoupdeVille ,and did greatly improved trailering for a very soft riding luxury car.Leaf springed cars/trucks are much better for load carrying than coilspring models .My 64 Lincoln handled trailering with it's leaf suspension as good as the Caddy with the bags.
