Well you mentioned the 4.10 gears with the hemi. I agree. I had a 6.4 with 3.73 and it always seemed like it was too low in rpm. That engine needs to have the higher gearing to be happy. What are you towing that you need the extra power? If you are just hauling your camper then the extra few horses isn't worth the price of getting into a new truck IMO. If you are hauling more then your camper and need the power get into a new diesel. I got rid of my 6.4 hemi for a new chev duramax and it was the best move I could have made. So much nicer to drive and haul with. I had a lance camper as well on the dodge.
