towing capacity for dodge ram 2500

stupid auto correct, meant gvwr. Thanks that is more helpful. I was towing a 6125 lb dry weight / 8313 gvwr rockwood with my truck with the 3.73. I have a friend that will do the gears cheap so that is not a big deal, we don't travel that far so mpg is not that big of a deal either. The main issue is, with the big tires it took off slow and was a little hard to climb hills with my old tt. We are looking at bigger ones but I don't have enough experience in the whole changing gears / lifted truck / tow capacity. We have been looking at a 8800 dry weight which will be about 10,000 gvwr but changing the gears, I think basically gets me back to stock towing capacity with the big tires. If that is the case, I don't want to max it out and be in the same boat I was in, instead I will stick with tt's in the 7500 lb dry weight and deal with it. Over 8000 lb are much nicer tt's, that's the only reason we have been looking at them.
thanks for the reply though
