I've got an 09 reg cab shortbed 4x4 Ram with a 4.7 that I pull an 18' steel deck car trailer with. It pulls just fine but steep grades give it a work out. On semi flat land it's great. Mileage is 12-14 with the loaded trailer. For the money I would go with the Hemi over the 4.7 though. If it's just an occasional hauler the 4.7 will do just fine.
