My trailer 245RBS Bullet weight around 5800 lbs. and pulled with a 2015 GMC 6.2 eight speed 342 gears. Always got between 11 and 12 mpg pulling in 6 or 7 gear at 60 to 65 mph
You got 11-12mpg pulling TT with the 6.2L motor? You may want to evaluate how you're calculating MPG. That's simply too high.
You might get 10mpg at 60mph, but 65mph+ pulling even an empty enclosed trailer at 65mph+, you wont see 11-12mpg.
Exactly as other have said, expect 8mpg-ish. You might see 10 here and there, but not often. And as low as 6 if you have consistent head wind.
You may want to evaluate how you know what someone else gets for mileage. lol I consistently get between 10-11 mpg towing an 8000 lb TT with a 6.2 / 8 spd. You'd be amazed how mileage is increased when you're on level ground and in 7th gear and turning 1700 rpms. Not to mention when it drops to 4cyl mode anytime it goes down a slight incline. I had a 2500 6.0 / 6 speed before this, and you're right, it got between 8.5-10mpg.
