It says it's an AWD, which I think means the transfer case can't be put in Neutral. So, doesn't that mean all the driveshafts, transfer case and tranny are turning when being towed? I thought you weren't supposed to tow an AWD vehicle like that. I would have thought the selectible transfer case put in neutral would have been a better bet.
Also, it says it has 62,000 miles on it, which comes out to average driving of about 15k per year. But, it's been towed. So how many miles are really on it? If it was towed by a motor home, then the bearings, hubs, rear end, u-joints, front drive shafts, differentials, shocks, ball joints, transfer case, etc. all could have a lot more miles on it. If the people put 15k on a year, plus they towed it, I would guess the chassis would have well over 100k on it. I'd pass. I think you are going to have suspension, bearing and transfer case related issues.
