Ram 2500 6.4 Hemi Towing a Fifth Wheel

First of all, there is no comparison between a diesel and a gas engine when towing. That's not what you asked. there also isn't much of a comparison between a GM 6.0 and a Hemi 6.4 I've owned both, I've towed with both and the Hemi is head and shoulders better than the GM 6.0 With that being said, I tow a 34' fifth wheel with a Ram 3500 with the 6.4 Hemi. It has done everything I've asked of it and other than the engine roars when going up hill, it's just fine. After a few hundred miles you can smell that the engine has been working but that's true with any gas engine pulling that kind of weight. A 6.4 Hemi will tow your 5th wheel just fine.
