Something is seriously wrong with that truck. The Hemi should pull your trailer all day long without even breathing hard. You have a little more weight with the 3/4 ton but not enough to make that much of a difference. A lot of folks here with Dodge half ton Hemi's pull a lot more trailer than you without a problem. Have you had the drive train checked? The power is there in the Hemi but is it getting to the rear wheels? What does the Dyno show the Hemi actually putting out? Quite the mystery, be sure and keep as posted as to what you discover. good Luck! :h
