New to me Gulfstream 8378

Im sure its been answered but what kind of fuel mileage can expect with the 8378 with the 8.1 with a Allison tranny. Im trading a 12000# fifthwheel. I only averaged about 8 pulling that with a duramax. So Im hoping yhe same. What do you think.

I have 2005 with 8.1 and 22,000 lb chassis, towing Saturn Ion i average 8 mpg...FYI the computer on the workhorse that computes mpg only uses the last 50 miles.. Read the manual closely.. Best way to figure is old tried and true measure gas in and gas out.... Good luck.....
