I wish I had used this one for the full amount of mileage that’s on it but I can’t take credit for it. I purchased it with just over 300k on it and it appears to be mainly road miles and I suspect it was towing most of the time. It had a goose neck hitch on it when I bought it. With 300k on it and at that time it was only about 4 years old so I doubt they had spent very much time inside of a repair shop. It was sold to me as a high mileage vehicle.
On the warrantee issue I had a company that was going to give me a warrantee for 100k miles. I bought it and then backed out. They did give me my money back because it was within the time frame they allotted for a refund. It may have been a good thing, who knows.
