I really need some help. I have a 2004 Dodge 5.7 Hemi and pull a Trails West Sierra II 2 horse slant. We would like to move up to a 3 horse GN w/ weekend type LQ. Of course we would still only be hauling 2 horses. Can we do a GN with this vehical or do we have to buy a 3/4 ton diesel? Looking for help and possible alternatives ie. air shocks, helper sprigs etc. Please any advice will be most appreciated.
Happy Trails

Do you have a 2500? What axle ratio? Which transmission? What does the trailer weigh loaded?

Sorry, I have the 1500 aauto trans with 3.73 rear end. Trailer, horse and equipment weigh in at just under 10,000 lbs.
Thanks

Yeah you are too high weight for your truck. Even with a Hemi 2500 and 4.10 axle, it would be close because of the double overdrive in that 545RFE 5-speed auto. If you had a 6-speed manual, it would tow better if you want to stay with the Hemi gas engine and not go up to a Cummins.
