Real towing experiencing with SRW

I ahve been in many discussions about SRW vs. DRW and it always comes down to this - what is your rear axle weight rating and how much are you carrying? Or how much will your rear ties carry? I can almost guarantee you if you will weigh your truck and trailer at a CAT scale answer these questions, you will have your answer. Overloaded - and the time to ask is it OK is not when going down the highway with the rig on back and you run over a piece of steel tread that a big rig has blown. You will in that instant think why did I not go with another rear tire back there when that one goes.
