Not to drift off topic but gas mileage has never been a concern as to how fast I drive.

I drive at speeds that I am comfortable at and the gas mileage is what it is.

It makes a difference to me. My next trip is planned for about 15k miles. Fuel costs will be close to $4000 at current prices. Cutting back a bit on speed can easily save me 20% or $800. That is in addition to a safer, less stressful trip. Of course I will spent more time driving, but probably not by much. Less stressful driving and better fuel economy means fewer rest stops and fewer fuel stops.

The best gas mileage I have got hauling my camper was 10.8 mpg.
The camper was empty, 180 miles non stop, cruise set at 72 mph.

Not so sure how much better it can get than that without crawling down the road at 55 mph. Something that I will never do.

But then again, $800 is $800. That's still a lot of money to us poor people.

My rig is about 13,000 pounds and I pull my camper with a CTD. I get about 13 mpg at 65 mph. If I drop down to 55, the mileage will improve only a little, maybe to 14 mpg if I am lucky. Increasing the speed is a different issue. At 75 mph I would be lucky to see better than the 11 mpg you got with an empty rig. It is not weight so much as wind resistance. Even a consistent head wind or tail wind makes a difference. I have gotten over 16 with a tail wind and around 10 with a head wind.
