Anybody have any thoughts on the hitch offered by http://www.shockerhitch.com/? I bought an H&H Speedloader EX and pull it with my 01 2500HD. I knew I overbuilt my trailer for 90% of my use. It has 2 6K lb axles and rides like the tires are octagonal when empty. Two companies have indicated that their air hitches would significantly reduce the vibration induced by the trailer. Just looking for some ideas. The Shocker is considerably less expensive than most of the other air hitches on the market. BTW, this is a bumper pull application, not a fifth or goose.
