Regrettably, I also think a new truck is in your future. Back in the "good old days" when the legal system wasn't so screwed up, you could get away with being overloaded a bit, and not worry. However, nowadays, with the juries and settlements being the way they are, I would be immensely worried about liability. As has been said, IF you are ever in an accident, and your rig is found to be exceeding it's limits, the lawyers will rub their hands with glee. And remember too, the insurance company only covers you up to certain limits, then it's out of your pocket. I just went through this concern recently, and it made me both buy a new truck that would be well within my needed weight range, AND also to buy an "umbrella" policy to further cover me. It's sad, but it's reality today! With so many crazy drivers on the road, you have to protect yourself as best you can. Adding a dash cam is my next step.
