What so many do not want to understand is that the truck has to be able to support the weight of the trailer pin. This weight limit is determined by the trucks GVWR and rear axle GAWR. The footnotes on the weight ratings state that all three weight limits are to not be exceeded...GCWR, GVWR and GAWR.
We meet lots of people pulling trailers that are over the SRW weight limits and I have yet to find one can tell me the weight of the trailer or truck and the axle loads. I urge the OP to get the loaded weight of his truck and see where he is on weight limits. He can then make an educated decision on towing and how much over weight he can be comfortable with.
And with this I am through and I think, I'll go make some pop corn.
