ditto. or a newer used yukon/suburban. My dad has had luck the past 15 years with Suburbans. Granted he buys them new but regularly puts between 130-150k miles on them in five years, tows quite a bit (his cobra, harley, and boat) at different times, and I think the biggest problem he had with the 04 he just traded in was his drivers seat heater stopped working last year, at around 120k miles. No engine/tranny issues, 4wd is awesome, he does snow trips for winter skiing, hauls my sisters shit to college and back, etc. And it seats 7 because he gets the captain chairs in the back, but you could opt for the bench and fit eight.
Oh and it tows 10,000lbs.
I've been contemplating a durango recently for our next large vehicle, but i'm not looking to spend $15k either.
