@Wake, I'd love to buy an Avalanche (I've been ******* after them for years) but what is driving the Tahoe/Burban/Yukon decision is that the wife and I want to be able to fit 4 passengers, plus the dogs (Husky mix, Shepard mix), plus gear in the vehicle. I can't do that with the Avalanche without having the dogs (or our other passengers) out in the bed and in order to crate the dogs in the bed I'd have to pull all the covers off and expose dogs and gear to the elements. Granted, there are ways around this, but it is a whole lot easier for me to open the rear hatch and say 'Up' and have the dogs jump in than it is to try and crate them and tarp everything down for a longer distance ride. That said, I am leaning toward a burban/Yukon xl just so I have more room behind the 3rd seat without having to pull it every time. I believe the 3rd row bench on these also folds, so I should be able to run some pretty long lumber in there without much hassle. If I'm missing something obvious here, please let me know, but the SUV seems to be the right choice.
We are keeping the budget small on this for that reason, if the the SUV ends up not fitting our needs the way the thought it would we will sell it and find something else without having to deal with the massive depreciation if we had bought a new Yukon off the lot.
