The HEMI is well proven at least in my eyes. I used to be a Ford guy as well, although I have no issues with them, I just found the 5.4L reminded me too much of the old 351M's. gutless. I now have my 3rd Dodge in a row, (first Ram 1500) i have 44 xxx on the ODO. I like it a lot. I have an 09 crew. I've had zero problems with it. It has had a couple of recalls, however its never had a failure. It blows my co-workers '11 chev away in every aspect. similarily equipped the Ram has a 100% nicer interior, more room, better fuel economy 5.7 vs 5.3 and about 100 more horsepower. I find the crew cab chev is a weak attempt. first time i tried to get out of the back seat my foot got wedged in between the seat base and the pillar and I damn near did a faceplant. And i can put a rearfacing infant carseat behind the driver seat without moving my seat ahead
IMO if you are wanting to change from a Ford the Ram is a no brainer.
