Never seen a post gain so much attention as this one on speed !! Seems that most folks are kind of sensitive about their speed. I can remember the oil embargo of the 70's, fuel rationing, long lines at the pumps and stations totally out of gas. When the speed limit was reduced to 55 most people adhered to it and I think some of them realized speed kills MPG on any vehicle. My last tow vehicle was a 96 Ford F250 with the 7.5 gas (460 cu in) and it got 9 and 10 miles to the gallon all the time. Once when running in fog early one morning after a fill up before hitting the Interstate I realized my fuel gauge was not moving much at my speed of 45/50 mph. I got off to top the tank and actually do a hand calculation and was amazed to see 14.4 mpg!! Speed kills mpg.
Yes people will drive miles out of their way to save a few pennies on the fill-up and then proceed to drive at a speed that adds almost $1 per gallon compared to going slower.

After 20 years of towing heavy, I've found my truck was designed to tow at 60mph. At 60 the engine is happy, the transmission is happy, the tires are happy and I'm happy. If you think I'm a danger, get your eyes and your brakes checked cause more often than not, I'm behind someone else doing the same thing.

Well after 8 pages it seems 60-70 is the desirable speed except for one or two that should know better towing 75 plus , but we see it frequently here in the west .

Wide open roads 75mph "EQUIPPED PROPERLY" is NOT a problem.

Wide open roads 62 mph "EQUIPPED PROPERLY" is NOT a problem either.

I like my chances a bit better at 62-65 then 75 plus . I have had a 21 foot boat start to sway back and forth at around 70 it was not a fun experience, kept it under control , but I was close to losing it . My 35 foot fifth wheel I would probably not be so lucky .

I can only imagine a maneuvering mistake with a 40 foot fifth wheel at 75, Oh well ! “EQUIPPED PROPERLY “ will save the day .

I just drove a 150 mile trip with the Redwood... 1st part was somewhat light traffic with 65 mph zone.... went with the flow at 65..

middle part was heavy, jut below the city, I did 55-60 in the right lane

Last part was moderate to light, again, stayed with the flow which was around 60-65 depending ...

For me, it all depends on the traffic flow, road surface, and weather conditions.

Properly equipped that is....

I know worker bees must travel at or above speed limits to meet their schedule for a vacation.
Some of us that are not any tight schedule prefer to use secondary roads and travel at a more leisure pace. In doing so I for one keep an eye on whether we obstruct traffic using shoulder and pull offs.
If you want to blast down the road, do so!

Gee maybe 50-55 would be better.
