ok well it looks like i am one step closer to owning a boat and looks like i might need some helper bags for the suspension (for my escalade ext 04). i know the truck has the autolevel system for the rear but am worried that the system will give out with constant releveling with the trailer. i was looking at the firestone airlift 1000 system? it is for my escalade ext that is lowered 3in in the back. wanted to know if anyone had any connections for this kit and air control system. i have been looking at http://www.performancesuspension.com/TruckAirSuspen.htm what would you do?
