Maximum tow speed for 6500 lbs Toy Hauler with two axles

We just completed our annual trip to a Hamfest, about 400 miles one way.
We always stop in Great Falls for the night, for two reasons: We have kids and grandkids there, and about 4 hours on the road is enough for me in my "senior years".
I drive 60 to 65, and now and then creep up to 70. That is fast enough for me.
"Fuel economy"? In our coach, with the Ford V10, there is no such thing, especially when towing the Jeep! I keep a log book with every fuel stop entered, but I have never bothered to compute the MPG. I know it is terrible!

We got back from our east coast trip 2 weeks ago chicago to New Jersey. Got my best ever mileage of 8.1. I averaged about 70 on the highway. I usually do 67 and get 7.5 and that’s here in the Midwest.

For myself I try to stay around 65MPH. I do this for a couple reasons, 1st it feels right and safe and 2nd Gas Mileage. At the best every 10 mile increase in your speed is equal to a 10% decrease in MPG. When you are only getting 10MPG a 10% decrease adds up in a hurry. I'm on vacation and its not a race. If you want to pull you TT 80MPH go ahead and in fact please get a head of me. Do you really think you are just as safe as the car next to you doing 80?

Just my Opinion, I have seen to many wrecked rigs in my life to drive that fast with a trailer.

Just because you can does not make it a good idea!!!

Happy Camping!!

What? Larry, Larry, Larry come on man. If you drive an 8 hour day that's 120 miles! That's a BUNCH over 2 or 3 weeks on vacation!

Or if you are on a 2 week vacation that's almost 1,700 miles!

And the whole gas fill up thing does not wash. After all, what happen to the "my bladder says I have to stop and not the fuel in my truck" crowd?

Some of you on this thread remind me of this video!Everybody on this thread needs to watch this video to understand MPH!

Bottom line: Don't speed, don't go over the limits of you or your equipment and you will be fine.

It seems trailer tire issues are incredibly common. In my experience, they just don't do well when loaded close to their max. I like to go up a size or up a load range. Once I get to 30% extra capacity, I haven't had issues. I routinely run 70 mph with no issues. Some trailers come with tires with extra capacity but most do not. My trailer came with the bare minimum in axles, springs, and tires. We go on long trips and are loaded pretty heavy, so I upgraded the axles and tires as well. Even before that I had LRD tires vs. LRC tires and even in all day trips through 100+ temps I never had a problem with the tires at 70 mph even with 65 mph rated Maxxis tires. My current tires are Goodyear Endurance with a higher speed rating, but I still feel better with the extra load capacity. They still run hotter than the rear tires on my Suburban.

Hi,
Going to make a 2000+ miles round trip within 10 days time frame and wondering if there is any problem if I tow 75 mph provided road is flat, traffic is clear and normal wind condition.
65 mph sounded like a norm to most people and I like to hear from seasoned RVers.
Tow vehicle is Titan XD with Cummins 5.0 Turbo.
Thanks.

My personal experience based on over 40 years and close to 200,000mi towing TTs is that towing much beyond 60 to 65mph is just pushing things too far. I can't point to any facts to support that just my "GUT EXPERIENCE". In reality with stops, etc. what you in reality gain from towing that extra 15mph doesn't really get you that much more IMO.

Nope, no issue if the truck, trailer and road conditions are sufficient.
I start drinking heavily if I have to drive overly slow....calms the nerves....
10mph avg speed difference over 2000mi is about 6hours of windshield time. That's a whole extra day's drive in some peoples itinerary, half day's drive in others and just plain longer duration watching cornfields go by and bugs hitting the window!

FWIW, I haven't had my drivers license for 40 years yet, but d@mn, it's been 30 now....ouch. From someone who averages around 50k miles a year behind the windshield, 90% of it trucks and half likely towing or hauling something it seems. I don't have the patience to "take my time" when just getting from point A to point B.

California has a speed limit of 55mph for trailers and towed vehicles.

Depending on the highway, they might allow up to 65mph even at the same posted speed limit of 55. But you don't want to know which is which as the state has the highest fines for traffic violation.

The most important consideration though is safety: for yourself, your family and other people.

California and their stupid split speed limits. Towing 55 all other 65 or 70, I guess that is fine if that was the actual speeds. In realality trucks 60 and cars 80 that big of difference is dangerous. So I avoid CA

I'm sure we will miss you on our beautiful lovely state.

10mph in a 10 hour driving day adds up to 100 miles. that's almost an hour and a half! and that is figuring in stops.

Read your sig line out loud to yourself and then imagine the average age and point in life of the average member of this forum and you'll realize why it may sound silly to them....
You (and I) have places to be and far busier lives than paw paw and me maw truckin from ArKansas to Casa Grande!
I wonder if I'll tell all the yungins when I get old that they're wasting their time driving faster and it don't take any longer to get there between overly active bladder stops and letting Fifi out of the kennel to take a tinkle and re-upping on the Metamucil?

Doubt it. I seem to be acquiring more horsepower as I age! LoL
