1500 Yukon XL Denali vs 2500 Suburban 8.1
Hello all, As you can see from my subject line, I'm contemplating making a change from my 2005 GMC Yukon XL Denali to a 2004 Chevy Suburban (2500). I'm looking for some real world comparisons ...

I have a 2003 2500 8.1L Suburban. I have towed nearly 4,000 miles with mine now since I bought it last fall. I've also done quite a bit of solo driving with it as well.
When I drove it back from TN, where I bought it, to MI I calculated around 12.5-12.7 mpg driving 5 mph over the speed limit (quite a bit at 75mph).
I think it would be difficult to get much above 13 mpg even if you drove 65 on the highway. 14 with a tail wind.
I just went on a 3,300 mile trip with my 7,000+ lb trailer (over 11' tall) and we got 7.5 overall counting the non-towing miles. Here were my tanks.
9.02, partly not towing before we left
8.26
7.72
6.56
7.27
7.73
8.42
7.39
9.51, mostly not towing while at Acadia National Park
6.86
8.39
7.24
6.99
6.41
7.19
7.32
5.54 (190 miles stuck in 2nd gear due to a loose wire in the fuse panel)
I live out in the country and driving locally, I only get about 10-10.5 mpg.
It tows great however. Lots of time spent in OD, plenty of power. Very stable, I have a dual cam sway control W/D hitch and it is very stable. I had some issues with the cams coming loose from the frame and had to run with just one side on a cam and the other side with a chain only for about 1/3 of my 3,300 mile trip and it was still very stable.
