Hemi 6.4 Ram vs Ford 6.2 (gas)

My 5er is near identical weight and length as yours. I just went from a 2005 Ford F-250 with the 6.0 PSD to a 2012 F-250 with the 6.2 gas. I love thus truck! Now with that said, I obviously don't have much time towing with it yet other than a few short trips. I pulled the 5er about 30mi on a test pull and have done 2 trips with my 24ft gooseneck loaded with a tractor both times which is roughly 8500# total. The truck performed great! My only complaint is the suspension is a touch weak in the rear. Apparently Ford went to a softer leaf pack around 2010-2011 to improve the ride. I plan on doing either the timbrens soon or a long add a leaf. Why they did this I have no clue, but they did. The overall towing experience was even better the the 05 mostly due to the 6 speed tranny that is very adjustable and versatile. I was about to have to put some serious money into the diesel that I just didn't want to. The initial purchase price, difference in fuel price, maintenance, expensive repairs, etc were enough to push me to change also as my truck is also my DD. Again, I have absolutely no regrets so far and am completely happy! I looked extensively at the big 3 and liked certain things about all 3. At the end of the day I just favored the Ford. Plus I found a fantastic deal on the one I bought and it's in mint condition with full warranty and Ford certified. I having just went through what your facing would be glad to help or offer my take and experiences if your interested. Just shoot me a PM and I'll help any way I can.
