gonna go out on a limb, and there is a chance i'm wrong, but 8mpg with that vehicle and toy hauler is VERY optimistic.
I have way over 100k miles towing a 24x8.5 race trailer that weighs about the same as my 2013 xlr27hfs.. but the xlr is taller. I have a 2005 diesel excursion in great shape. i tow all over the flat as a pancake state of Florida (almost zero hills/incline). I RARELY ever go above 70 mph in the interstate. the best i do is 11mpG on the highway. If i have to drive around the city a bunch with the trailer, it's worse. With the xlr27hfs?? it goes down to 10mpg unless i back er down to 65mph.
I had a lincoln navigator years back pulling a 7x16 dual axle trailer (weighed way less than a xlr27hfs ) .. i got SIX-SEVEN mpg with that thing even at 65-70mph .. LOL !
I would take some more readings towing the xlr in your Dinali but be sure you reset the thing from any driving prior to towing.. or better yet, be sure your speedometer is correct, and do the math the next time you fill up
