I bought one!
Just bought a 2004 Yukon XL 2500 with the 6.0L. It has 110k miles on it and is in great shape. I had been searching high and low for a V10 Excursion. After checking out a few it just seemed like they were all more worn than I wanted - and expensive! Then my dad sent me a link for a hideous green (state park vehicle) 07 2500 Suburban. It only had 80k miles but was out of my price range. Turns out, the same place had the 04 I ended up buying. I hadn't really been looking at Suburbans or Yukons because the few times I'd searched for them I found nothing viable for me (either too far away or too expensive). I'm extremely excited and happy that this one came my way.
It needs a couple small things. Looks like the oil pressure sending unit is bad and maybe the trans temp gauge isn't working. I'm really excited to go to town giving it its inaugural detailing - something I've always loved doing to a new to me car.
I've never driven a heavy duty truck before. So, it was a bit different of a feel. When I put it in 4wd it was louder than I had experienced before - not bad loud, just noticeable and different.
I'm going from a 2001 Nissan Xterra, that I love and thought I'd drive until it fell apart. But, our plans changed. My wife and I plan on hitting the road to live full-time in our 33' travel trailer with our 1.5 year old daughter, dog, and cat. A bit crazy, but it is ultimately what brought me to this forum.
I'm super excited and anxious to pick it up in a few days (getting a power lock fixed first)!
