Here in Kansas I've been bragging up the 09-newer Rams pretty hardcore in regards to rust or lack thereof. We have many many 2010-2011 (or newer) gm and Ford trucks running around with bedside and cab corner rust but the 09-12 rams have been holding up great. I have seen exactly one 09 ram with bedside rust starting and the jury was out on it anyway (repaint). I know it's coming and it's a matter of time before the oldest ones start bubbling but don't think for a second you'd fare any batter with brand X. They're worse. Far worse.
