Any one have experience with the GMC quadrasteer? Looking at a Yukon XL with 90k on it, 3/4 ton, quadrasteer, 2003. From reading the posts about the suburbans, I would say this truck has plenty of life in it. I have never kept a truck past about 110k, as the dodge and ford I had fell apart at that point. Currently, my chevy has 60k on it and has been great, but I want the 3/4 ton for towing and they are hard to find. Any thoughts.
