I have an 06 2500 4x4 with afe intake and filter and mbrp exhaust. I also have a set of air bags with an onboard compresor. I am purchasing a 33' warrior fithwheel with a gvwr of 15000#'s. I am looking in to some sort of programer but have no idea which way to go. I will use the trailer 3 or 4 times a month in So Cal. Also would any transmission mods be in order? Any help would be great.
