Hello, I went for a test drive last night in an 06 YXL Denali. All of us in the vehicle (me, my son, and the salesman), noticed that upon getting onto the freeway, the vehicle ride had a very noticeable and rhythmic bounciness to it. I had previously test driven both a regular Yukon Denali and a different YXL Denali on surface streets only, and there was no bounciness to either. So this was a new experience. I called my Dad, who's been a round quite a while (70+), and he said that GM truck frames with long wheel bases are known for having that bounciness to them on concrete freeways. He said that if you have it all loaded down with a full tank, gear, and perhaps a trailer, it goes away. He also said that if you drive it on a blacktop highway/freeway, instead of concrete, the rhythmic bounciness does not occur. Have any of you experienced this? I tried searching on "bounc" (to catch all forms of the word), and didn't find anything with any answers. Is there a way of cancelling this bounciness out using any features of the YXL Denali, such as AutoRide? Is that something that needs to be activated? Or is AutoRide always on? Unfortunately the salesman was absolutely clueless about the Yukon and YXL Denali features. Didn't even know how to use the Navigation, so he couldn't show me its various capabilities. I'll need to find a different dealer. I like the extra cargo space available in the YXL Denali, and I wanted to give it serious consideration, but that rhythmic bouncing really bothered me. I want to be able to take it on various excursions with or without a trailer and have a comfortable ride. Please let me know if you have any ideas. By the way...what's the story on using snow cables (not chains, but cables) with the 20" rims/tires on the Denalis? Any issues? Thanks for any assistance you may be able to provide. Mike

I'll most likely be purchasing a Denali or XL Denali in the next day or two (looking like XL Denali at this point). I've researched other postings on wheel size and have come to the conclusion that going with the 20" rims/tires is asking for trouble when doing any sort of off roading (I'm just talking unpaved dirt roads, nothing crazy), as well as having more flexibility with snow cables, and handling pot holes without damaging the rims. So, I'll stick with the 17" stock wheels/tires for the purchase. However, I'm still interested in getting an upgraded wheel/tire via aftermarket that upgrades the look, and that can still handle the unpaved roads, snow cables, pot holes, etc. Has anyone found a comprise along the lines of an 18" custom wheel/tire rig? If so, is there a good online vendor that you could point me to? I live in Southern California, so I imagine there may be several outfits down here I can visit, but it would be great if I could at least see an online catalog to choose from. Any help is appreciated. Thanks. Mike

Well, I took the leap and purchased an 06 YXL Denali with all the options (NAV, RES, Sunroof, buckets). Very excited! Regarding break in of the vehicle. Just how important is it to not go over 55 mph, and to not shift down, during the first 500 miles? I'm fairly certain that both of those things have already happened just in the course of the dealer transferring the vehicle from another dealer. The freeways here in Southern California have everyone driving at high speeds (70+), and I'm willing to bet that whoever drove it down could have easily used engine braking at some point. The vehicle had about 100 miles on it when I took delivery. Regarding the topic of being towed. The manual clearly states that the vehicle cannot be towed, otherwise the drive train will be damaged! Now, given that every vehicle I've ever owned has been towed at one time or another, I just want to make sure I understand what they mean by towing. The manual talks about the fact that the wheels cannot touch the ground while being towed. So, that means towing the vehicle should always be done via a flat bed truck. I'm ok with that. However, what about just moving the vehicle at slow speeds, such as when getting it up on the flat bed? Or what about pushing it out of my driveway to jump start it? What about getting pulled out of the snow or mud via the recovery hooks? I guess I need to make absolutely sure that the vehicle never "coasts" in neutral at more than a walking pace. Sorry if the questions seem silly. I've never owned an AWD (or even a 4WD), and I'm excited about using it for family treks to mountains, snow, trails, and good old road trips. I want to make sure I make the thing last and keep it working well. Anyway...any info you have is appreciated. I'm also going to call the dealer and see what the service guys have to say. Thanks. Mike

I'm interested in bumping up the height of my new DXL a few inches, just so that I can get some better ground clearance for the occasional trails that have some deep dips, as we make our way with the bike rack (with 4 bikes) on the back. Has anyone here done anything like that? I've done a little research on it, and it appears that full blown suspension lift kits aren't available due to the autoride (nor would I necessarily want such a major modification). I've heard of something called a "body lift", not sure about the difference. Any insight is appreciated. Thanks. Mike
