We have an 04 GMC Denali XL- so the gmc/denali version of the suburban. I love it. I was so against it at first, wanted something smaller, but now I love it. We have the 2nd row captains chairs which are nice- makes it easy to get to the 3rd row. I like that my kids can be in their carseats, and my husband and I can still fit 2 other adults in the car. And unlike the tahoe or shorter version- you still have all of that trunk space. The short versions, when you put the 3rd row in, you've lost all of your cargo space. We bought it used in 06. Speed sensors were having issues about a year ago, we had them taken off and cleaned, and have been problem free ever since. Other than that- in the 5 yrs we've had it, just regular maintenance. Tows great. We used to have a 28 foot powerquest boat, towed it no problem. Pulls the wakeboard boat without an issue. Been up north (even to Canada) who knows how many times pulling sleds. Not so great gas mileage, but it's a big V8, that's what you get.
