I'm in the same boat. A '99 Yukon with 178k in pretty good condition. I paid 3,400 for it 18 months ago and have put another $3k-$4k in it. It did very well on a 5,700 mile trip to Maine and back with a 27' camper on the back. We're heading to California but I don't have the same level of trust as I did last summer. I'm not sure why, but I feel like I'm pushing my luck with a second, long trip with 5k pounds on the back.
I had the front seals replaced yesterday after having them done 11k ago. The shop did me a huge service by standing behind their 1 year warranty even though it was a week past the 1 year period. It needs front brake rotors, but that is it mechanically for now. My dilemma is very similar - sell it and take an assumed loss or put my trust in it. Not sure what to do. There is no right answer.
