My Avy is just over 250,000 miles... Still running strong.. The rear end has had some issues which have been mostly taken care of but other than that the only issues I have had are an Impact sensor, the cluster going out, the mirror display for temp and direction is intermittent, knock sensor, intake manifold gasket and I am sure I am missing some other minor stuff.. I bought it with 185,000 miles on it.
I have also redone the brakes, upgraded to the 900 brakes in the front and also had the transfer case and transmission rebuilt as precautionary measures. (Had the money and thought I had issues with them... Worst case, they won't go bad for a long time now.) I also put different tires on the truck and had the rims powder coated but those were not required either. Just wanted it to look better and I wanted to get new tires while I had the money for it.. (Figured I would have extra cash for a little while so I thought I would make sure the truck would last a while without any major repairs needed.)
