Hi TDR..... I am new here. Long time RAM truck owner, first time Diesel owner. I purchased a 2012 RAM 2500 Laramie automatic with about 25k miles on it. We have had it about 3 weeks now. I love it. Geeze this thing has bells and whistles I haven't even discovered yet. We have a small toy hualer that my 2003 HEMI would tow.... but it was NOT happy about it. LOL. I haven't towed with the 2500 yet.... but I'm looking forward to keeping up with traffic, especially on the hills. I have added a spray in Rhino liner, Access Limited Roll bed cover..... and Edge Evolution programmer/dash pod. I'm not sure what else, if anything, I'll add. I have to say the Edge programmer really feels good.... initially I set it to level 3 for performance, but I'm sure I'll set level 1 for economy 80% of the time..... level 2 for towing the remainder. Thanks for listening! I am looking forward to learning from you all.
