Hello, a newbie from Vancouver. I stumbled accross this sight when I was looking for info on a new tow vehicle and found some very informative comments. Everyone seems so friendly so I figured I should join - probably should have joined sooner A couple of years ago my wife and I wanted to try RVing and we were on a budget so I bought 99' Astro and a 18 ft starcraft travel trailer. The Astro was obviously loaded to the max with wife, kids, dog... and we'd like a larger tt with a slide, so it was time to upgrade the tow vehicle before I upgrade the tt. I searched for months to find exactly what I wanted and finnaly found it and bought it a couple days ago. It's a 2006 Yukon xl 2500 8.1L 4.10:1 axle only 75,000km (46,500miles) fully loaded and it looks like it just came off the showroom floor. I hear these things can tow OK lol. It has a K&N cold air intake and came with a Hypertech tune so power shouldn't be an issue. The fuel milage is exactly where I expected it after reading real life use stories (12-14 mpg hwy), its a second vehice so unloaded fuel milage is of little concern to us. Cheers!
