I am pretty much like everyone else out there.
I try to run at 65 and will switch in & out of Cruise Control based on the traffic flow and terrain!

A good rule of thumb is that for every 10 mph increase in speed you will see a 10% decrease in fuel economy.

I have only towed with my current set up around 4000 miles. So believe it or not I am still working on finding the sweet spot. I suspect that it is right around 63 - 66 mph! When you don't run the same route all the time it can be a bit tougher to dial it all in.

For those of you that tow at 80 - what the hell is your hurry? If you are in that much of a hurry take a plane! !

Happy Camping & Safe travels!

Pretty simple math. So many miles and only so many days. You need to talk to my boss so I can get more days.

Do the math on a rather long trip, You might be surprised to see that only hours can be saved, not days. Don't forget to factor in all those delays caused by slow pokes like me and others that commented.

My experience is with two separate RVs. On each I got a 50% increase in gas mileage for a 14% decrease in speed.

1. Class C on an E450 chassis - 70mph and 6mpg vs 60mph and 9mpg

2. Airstream TT behind F-150 - 70mph and 8mpg vs 60mph and 12mpg

I drive Memphis to Colorado Springs (1,000+ miles) to visit my sister.

I believe this. I got about 14mpg to Bend OR and back with the camper on the truck driving slower 2 lanes. 65-70 tops for most of the trip, sometimes slower, little 75+ on the freeway.
Straight to Spokane and back at 80, I get 10-11. Less if there's a headwind on the way back.
Noone doubts that driving slower burns less dinosaurs....but

I tow at whatever is a safe speed for the road conditions and traffic conditions. (also taking into account the max speed rating of 75 MPH on the trailer tires)

Usually it ends up being between 65-68.

I do get significantly better MPG at 55-57, but over 7 days driving, that extra 10 mph slower would make it 8 days of driving instead of 7.

RE: the OP concerns of "getting run over"... never had anything like that happen/or come close to happening. Even when in SD or Montana where most everyone is running 85-95. They just go around me, never had anyone run me over. [emoticon]

If they're jammed up because of a slow moving semi, if it is safe I will speed up a bit to lower their blood pressure. But they couldn't "run me over" even if they decided to try.

When not towing the trailer I ride a motorcycle as my daily driver. I do what is safe for me...on the bike and in the truck. No small part of that is staying away from the herds/clumps of vehicles all traveling fast and too close to each other.

I ESPECIALLY put a lot of distance between me and a truck pulling a trailer at 75-85, wagging their tail down the road.
