Are those tires ST type tires? I'd bet they are. If they are, there is a 99.999% chance they are speed rated to only 65 mph.

While going over 65 by 1 mph isn't going to cause one of those tires to blow up, then changes of one blowing up starts to escalate the longer you pull at a sustained 70-75 mph.

Another thing is that I'll never get why so many people tow at 70-75 mph? What are you thinking?
A 4500# boat/trailer will get better mpg than a 4500# travel trailer.

I agree about towing a trailer at 70-75. Nor do I feel bad for anyone towing at that speed that gets really poor fuel mileage.

Wouldn't it be silly to put ecoboost technology in anything smaller than a 5.4? (Regarding Superduties) Guys who pull heavy loads everyday (Hotshot, Farmers etc) would sure use the RPM's.

You actually believe what a salesman told you??? I have a bridge for sale that I need to show you.

Air the tires up on both the truck and the trailer, to the maximum stated psi on the sidewall. Slow down at least 5 mph (I'm betting you're running a lot faster than 60 mph), let the rig lose some speed on uphill stretches, and gain it back on the downhill. Do not use cruise control, it's a fuel mileage killer. The biggest factor in fuel mileage is the driver. A buddy of mine has exactly the same truck that I have and I get 29 percent better fuel mileage than he does with the same load. Make all of those changes and you will get significantly better fuel mileage. I use all of those techniques and I get great fuel mileage.

What I do expect is what my salesman and service writer told me ( and continue to tell me ) I should be getting , and that is not 7.5 mpg
