Well unfortunately I get to go inside one, not my choice, but parents couldnt afford a duramax, so they bought a powerstroke instead. Whats common to see worn in these, is transgo good for these? The truck is primarily hooked to their horse trailer, depending how they have it loaded, 10-15k weight, weekend warrior. He has a Bully dog on it, nothing serious for power, but I would like to build it right, where he never has another problem with it.
