Every time that I think I have a handle on these, they seem to explode in my mind. I know what each of the letters stand for, Gross Combined Weight Rating,........etc., and I know what they mean. What...
Clev, no matter where you consider the pin weight to be, you are still over your gross combined weight by a fair amount. Yes, I think due to the 3.55 gearing. If you tow in 5th, lockout 6th, I don't see a problem. In any case, watch transmission temps, when pulling hills or head winds. I would not be too concerned, unless you feel you are straining your drive train, in adverse conditions.
