Your numbers towing are accurate based on my experience as well. My truck was a dually and empty got around 9 -10 ish basically no matter what I did. If I could get 12-14 like you empty I would have been ecstatic.
Since you mentioned the 8.1 your buddy had.. may I ask what the MPG for your friend was? I have been considering an 8.1 in a Suburban recently. I suspect that the MPG's between the V10 and the 8.1 are relatively comparable. But I am not sure.
Thanks!

I just sold our Yukon XL with the 8.1 and 4.10 rear end. I was right at 10mpg in suburban traffic and around 12ish hwy solo. Towing a fairly high profile TT weighing 7500 ibs I'd get 7-8mpg going 65mph, if I went really easy and slowed down I'd get 8-8.5mpg. But she didn't labor at all, nice easy towing. Spent a lot in gas, but it was waaaaay cheaper than a diesel and towed our rig great.
