Poor fuel mileage towing the toad

So I'm almost home from my 1200 mile excursion, and I'm a bit disappointed in my fuel mileage. I didn't track the first few tanks but I'm guessing they were less than 7mpg. The first tank I tracked was 6.5, and the second was 7.5 (while trying to milk it by slowing down my pace to 55-60). The first tanks were pedal to the floor the whole time. I avg about 60-62 mph at 2400-2600 rpm.

From what I've heard from the previous owner and other Genesis owners with the dt466 mt643 combo, I expected a bit better. Am I hoping for too much with the toad? It only weighs 2600 pounds. I also have a motorcycle and a small 300 pound trailer inside. As well as some furnishings.

I'm a bit discouraged, let's hear your input

So getting half the normal mpg towing 3k pounds is normal?

10-12mpg without the trailer is average

i'm around 7mpg towing, pedal to the metal (65ish). if i slow down a bit to 55ish, mileage goes way up. i just don't like going that slow.

Signatures don't show on the mobile site for me. Well with me having the mt643 I would think I would get a little bit better, but you also have a smaller displacement. So maybe that's what makes us equal

when i hear 10-12mpg on this forum and others, i kinda roll my eyes. its wishful thinking, maybe once in my ownership and doing the math, i've come around 9.?, which is close enough for me to say 10. i also have a generator that runs off of the same tank, so that makes my numbers go down as well.
i keep the pedal on the floor when i drive.

How well do you get along with that AT545 in the mountains?

the first few times i was unprepared for what happens. its a scary learning curve. now with some practice i'm much better.

1st time descending i-70 was a white knuckle, change your shorts trip. once coming out of rocky mountain national park, i caught the rear brakes on fire.

you cant depend on the transmission or your brakes to slow you down too much, they dont. you just have to go slow, or get a bus with a retarder.
