Pulled with both and stayed with gas for personal reasons.. The gas job does fine up to 10k for my use, have no complaints, will drop a gear or two on the steep hills and run around 4k rpm. No worries, keep up with traffic fine. Diesel will be easy to pull with when ur trying to pass other cars or trucks. But when it comes down to repairs.... Well diesel will eat ur lunch no matter what anybody states. They are very expensive to work on especially the newer generations. Now going back to the older ones is a different story. Regardless, it's your money spend as u need to. Diesel and Gas engines have their own advantages and disadvantages. Good luck on ur search, this topic has been brought up millions of times. It comes down to personal preference/money.
