I had an older model gm gas 3/4 ton
I now have an dodge diesel 3/4 ton.
I enjoy pulling much better with the dodge diesel 2005 model, so much more power and better mpg.
I know mine is much lacking in power compared to the new models, but I think you will enjoy the power of the dodge diesel engine.
I have 72K miles on my truck and it has been a very good truck, my wife can handle it fine pulling the trailer.
man-o-man that diesel engine has the power, maybe its just the kid in me. I may be 65, but I still like to roll some coal from time to time.
