Other than the problems noted above this vehicle has been a joy to drive and own except for the gas mileage. I truly enjoy traveling in this vehicle and we put a lot of miles on it with family and hunting trips.
The kids keep entertained on both short and long trips with the DVD player, and I can listen to XM radio at the same time while they are wearing their headsets. Also, when they do get a little older, it looks like I can plug a video game into the DVD monitor.
At speed (read above 60 mph) the 6.0L engine has no problem pulling a fully loaded vehicle and trailer down the highway and through the hills. Passing and getting on the freeway are not a problem. But you can see that instant gas mpg is in the single digits, if not less than 5 mpg.
There are too many features to list and comment on, but I will say that I was talked into buying the Denali over the SLT. At first I was not too excited to spend the extra money on top of what it would cost for the '03 Yukon XL SLT. But now I would do it again. I just hope that as the vehicle has more miles added, it is not too expensive to maintain. Our '95 Yukon SLT has over 200,000 miles on it and I have not spent too much to maintain it. With all of the added features on the Denali, that may not be the case.
