65 for us unless we are in California then it's 58 to 60, max tow speed in CA. is 55 mph . I am sure some other states have the lower speeds for trailers. I was running 62 on US 395 along the Eastern Sierra and actually had a CHP pass me after he followed me for about 5 miles or so.

I travel I-95 a lot and quite frankly anything below 60 is a hazard to traffic as the right lane averages 70.. Upgraded tires "G" and set cruise 67-68. I know that we have the right to go 55 in the rigjht lane, but I see how traffic has to shift and bob to get around. particularly where there is only two lanes per side.

Yep, most ST tires are only rated for 65mph max. Exceed 65 and you'll probably have hot tires and shorter life expectancy, or worse experience a blowout. If you want to tow faster than 65mph you need to invest in LT tires. WRT crosswinds, if you see commercial trailers leaning, it's past time to stop for the night.

When on 95 I just tuck in with a pod of governed trucks doing 65. Fast enough.

Traffic is just going to have to shift and bob. I am going to put her at 60 MPH and let her ride.

I kept ours at 60-62 for most of the 3000 mile trip on my recent military PCS. My TPMS on the trailer tires showed temp increases with speed. Side load from the wind also increased tire temps a few degrees.

As for wind, there was a stretch in eastern South Dakota that scared me into slowing to 50 mph for a while when crosswinds climbed to 35 mph. The sudden gusts can really make one side light, and that's not a feeling I like. The semis seemed to agree, as they did the same.

Overall, I enjoy towing our 5th wheel on the open road. Like a previous poster said, I just pull in with the semis, set the cruise at 60-62 and let the rest go on by.

My comfort zone is 60 to 62. The winds out west can get tricky, I went through the gap at Chamberlin SD, and the cross wind actually moved my motor home. Was only doing 50 at the time and the trucks were listing badly.

Only one post referreed to "posted speed limit".
I have a class A MH and tow a car. I was informed that I qualify for
the posted speed of "vehicle towing".
Being a Canadian travelling in the USA, I set my speed at 60 and leave it there.
I talked to one officer at a rest stop about the 55 posted and he said that he considered 60 to be the "safe" speed.

I am retired and enjoy each and every mile

With the correct tires that are speed-rated, and weight rated for your RV, and a properly matched tow vehicle, you can tow at traffic flow speeds and be safe. BUT there are your personal driving skills to take into the equation- can you control your vehicle if "Blank" happens?
We have towed at 78mph for hours on end crossing Texas. We were actually being passed regularly by faster trucks- semi's- pulling 80 or better. But we also have a very capable tow truck, rv tires, suspension, and I'm comfortable at those speeds.
Coming east across 40 last week.... I ran 68-75 depending on traffic. Not holding up the right lane, but not passing everybody either. In cities move to the middle of the 3 lanes and go with the flow... sometimes it's 60mph, sometimes 80!

My pulling speed is dictated by, road conditions ,weather,traffic load,speed limit, and most of all, common sense. My speed ranges between 55 mph and 70 mph max.
There are a lot of 2 lane roads in mountainous roads that I haven't been able to do the speed limit, due to sharp turns, and narrow roads. I always pull over as soon as I can. On the other hand if I'm doing the speed limit I don't worry about it so much.

Thumbs up

Up here in Canada we have the Coquihalla highway, posted speed of 120Km which I believe is 70 MPH, there is no way I am going to go that speed, max for me due to tires is 65MPH and my own personal preference is around 60 ish, wife complains if I go too fast anyway, so would not get away with higher speeds even if I could, plus as was said, I like a relaxing drive and being able to take more in.
Live life with no regrets.

The speed limit is my governor, whatever it happens to be. I slow down for wind and park if I start seeing blown over vehicles.

I too am retired so what's the rush. Do to speed rating of ST tires I tow at 65 mph. That's 65mph on my GPS that equates to 67mph on my speedometer.
Happy Camping

On our 8000+ mile trip all over the US this summer, I have towed at 60-62 mph except in rolling hills where I have found if I go up to 65 the truck will not kick down into 3rd on every small rise as the rpm is in a better torque range. I have also averaged over 11 mpg. We are not in a big hurry to get anywhere. For us it is more about the trip than the destination.
