Just traded my 1500 for a 2011 Chevy 2500, with tow package (tow mirrors and brake controller). I do not have owner manuals yet do the factory brake controllers work the same as my P3 controller?
I've also been looking for my 5th wheel TV and the Ram 2500 Cummins and Chevy 2500 Duramax are the 2 I would consider. I have heard that the Allison transmission can be a problem (was disappointed to hear that) but it was only from one person who's son had that vehicle so I don't give it much weight at this point.
But should I get a transmission cooler if the truck I find does not have one?
