I had a Chevy 3/4 ton 08 with the 6L gas engine and my buddy had a Ram 06 1/2ton with a hemi. We got very similar mileage towing the same trailer but my 3/4 was more stable. You couldn't use cruise control at all. We both bought diesels, me a Chevy, him a Ram and both are very happy! Look for a newer used diesel!
