Im conflicted about what to do here, I have an 07' Titan 4x4 without big tow that is obviously not going to be able to tow the travel trailers I am looking at buying. My one option is to beef up the rear end (that I think is going out anyways), transmission, and suspension on the truck I own or buy another (which I really don't want to do). Reading around on the site i've settled on a lvl 10 transmission, radflow suspension all the way around with an extra spring on the rear and possibly TrueTrac rear end. I cant seem to find the common point of failure on these rear ends and if the TrueTrac is actually going to help with it or if I should just look at a different route. Is the truetrac the way to go?
