2006 Dodge Ram 2500 v-8 gas toeablility

The 5.7L Hemi will spank the **** out of the 12v Cummins at lower altitudes unless it's been modified. That is however, at high rpm. I'm a fan of the Cummins as well as the Hemi but, I wouldn't want to tow that much weight with the Hemi. We towed our 10,400 lb actual weight high profile Jayco 5th wheel all over the southeast with our '05 Hemi powered 2500HD Ram. It did a fine job but Monteagle was the only pass we crossed with it. The rest was just rolling hills. 2700~rpm on the flats and 4200rpm on the uphills. It won't hurt the engine but cringe will give you a migraine and ruin your trip. Didn't bother me a bit but most folks wet their skivvies at the first downshift. I liked the sound. I traded my like new Hemi Ram with 120k miles on it. Didn't burn oil and still ran and looked like a new truck. Nice find but I vote no for that amount of weight.
