I'm like you in the fact that I used to be a Chevy Guy. That was until I bought my first Ram (03 SLT Hemi Quad-Cab). I couldn't believe what I had been missing. Since then I have bought a 1999 Ram 2500 with the 8.0 V10 and I must say Dodge has really been impressing me. All the negative things I have ever heard about Ram trucks were quickly put in the dust. So personally you're in for a treat with the Ram IMO.
The only good thing Chevy has produced has been the 6.0 and as far as Ford they make awesome milkshakes. Plus have you ever heard of anyone doing a Powerstroke swap??? I haven't either.
