The other day I loaded my truck down real good see sig. I was pulling my trailer that has about 700#'s of ball weight and had at least another 1000#s of debris in the bed. This should be at or over the limit for my truck including my toolbox and other stuff in my truck. my point is that my overload springs where barely touching the rubber stops. I am not complaing how my truck handles loads it handles them almost as well as a dually, and the ride is better than a cad with this much weight but seems weird they would make these trucks so the springs just start working when you have exceeded the max weight for your truck.
