Im not sure if this is where this topic belongs but ohh well. I am wondering what is the most that anyone has towed with their 355. Im planning on getting the air bags for the rear suspension. (Leaf spring to frame) Eventually I want to tow my 18 foot open, steel car trailer with my 70 chevelle on it to the track. Obviously the trailer has electric brakes and I will be installing a brake controller on my truck.
