Interstate cruising speed

[Boatbuilder]

When ulling I usually don't go over 65 but when I am not pulling depends if I am in a hurry or not but usually not over 75 .

F350 6.7

[Red Wolf]

65 on the dot if on cruise control, regardless if the posted is higher. That's been true for the pop up, the Jayco bumper pull, and the 5th wheel for the past 20 years.

Fuel economy and safety.

I am answering the question I read. Speed limit through Missouri, Illinois, Kentucky, Tennessee, 65 to 75, passed no less than 4 highway patrol while cruising at 79 mph. When I am pulling a fifth wheel I never go faster than 60. I want plenty of space between me and the idiot in front of me (you know who you are).

[Jimhinkle]

65 to 70

[KNMIB]

In a 28 foot Motorhome not towing I run 70 until the wind hits then I drop accordingly.

[Woody1959]

I have a small TT and I keep it 65 or less.
I’m surprised no one mentioned to keep in mind what your TT tires are rated for.

[Lifestylers]

GO fast so I can miss the scenery and run over the slow pokes.

[FORKLIFMAN]

70 to 75, with or without the toad. only because it wont go any faster! Motor shuts down @76!

California is 55 MAX towing but regardless I set the cruise at 60 MPH and don't rush when towing. Better mileage and my tires last a long time. I know I'm due but my current (Goodyear) TT tires are 13 years old. I only put about 700 miles a year on them because our destinations are mostly close. The spare hanging on the back is the original brand new never used Goodyear that came with the trailer when purchased new in 2000. I plan on replacing them this year before summer. No nitrogen in the tires and I usually only have to add 2-3 lbs after sitting for up to 6 months.

I'm a 65-67 guy fuel is good there after that it plummets. However going across desert long boring stretches maybe 75 if I'm getting impatient.
Trailer tires are rated to 101mph so safe there!

[NWeagleGuy]

Most states, the max speed for RVs is the same as the posted truck speed limit. That and the max speed of your rated tires.

[-lenny-]

My trailer tires are rated to 75mph, so I don't exceed that. I generally just go with what's comfortable, while trying to ignore my fuel gauge.

PS I HATE towing in California. I find it absolutely painful to drive that slow for no reason, and I can't see it being any safer when the rest of traffic is travelling 20mph faster? But I sure did get amazing MPG...

[mds47588]

65 mph w/cruise. And some good music and a cold Diet Coke to make the slow speeds more bearable.

Myself I like 64-65 mph.

60-65 always best milage and handling. 2005 Class C Ford E450 6.8L. Going to do a 5 star tune to help with shifting and milage.

If you're not going at least the posted speed limit in good conditions like that, you are becoming a traffic hazard, as most of the traffic will be going at least the posted limit, if not faster. I really don't like tractor trailers barreling down on me if I'm going too slow for conditions.

I drive 60-65 on Interstate with no problems. That's what the passing lanes are for. No problem with semis.

[CurtPutnam]

Our truck seems happy at right around 62 +- 3. Less in wind and on curvaceous roads. The Maxxis 8008s on the TT have a stated limit of 65. Traffic always slows us down. Note that in CA the limit when towing is 55, although the CHP generally provides considerable leeway.

[nrkmann]

55 - 60 because I travel a lot in California and ST tires are nomilly rated for 60 mph.

[Bob Springer]

65-70. My tires are rated for 70 mph.

[ChrisParise]

Cruise control set to 70. Tow/haul on. When I start up a grade I put a little pressure on the gas pedal and get my speed up tp 73-74 so I dont downshift.
If the grade is too steep, I cancel the cruise, and tow/haul if I need to, and do my best to maintain speed without flogging it.

I feel more comfortable and more in control at a slower speed. My max is usually between 60-65 mph. Plus me dog is more comfortable at a slower speed, less road noise.
