Hey Mikendebbie, love the curvature of the earth comment. LMAO!! I run at 65 and no faster. I have a retired Fire Captain as my best friend and he has told me of many calls he went on during his career that involved 5ver accidents that resulted in serious injuries or death to both the occupants or Rvs that were caused by excessive speed. In my younger days I pulled many triple axle 30' plus go-fast boats and had many tire failures along the way...and couldn't figure out why...DUH!! I learned the hard way. Experience is the best teacher.

My preferred speed is 68 mph. The fuel mileage is not bad at that speed. The wind resistance towing a huge square box down the roadways takes a lot of fuel. My fuel mileage is between 8 to 10 miles per gallon. Towing with the weight I tow is around 26,000 +or-. Increase speed consumes more fuel. When I tow with just the Truck, equipped to travel, the mileage is between 16 to 18 more per gallon. Again thats at the speed limit. Good luck

Happy trails.

Drove semi tractor trailers for 13 years before going into the Navy. Found out early on the difference between pushing the envelope all the time and settling in at around 60 mph equated to one extra cup of coffee while at the truck stop. YMMV

On the multi lanes, I try to follow another RV or a tractor trailer that’s doing no more than 67 - 68. I can keep a safe distance between us usually without someone jumping in right in front of me. Once they see the rig in front while passing us, they just stay out there to pass them too.

Time Saved By Speeding
Ever wonder exactly how much time is saved by speeding to your destination?
I did a little figuring and the results may surprise you.

Chart #1
Miles MPH Time (in hrs) Time (in mins & secs)
10 55 .181818 10:55
10 65 .153846 9:14
10 70 .142857 8:34
10 75 .133333 8:00
Chart #2
Time saved every 10 miles by going:
65 instead of 55 .027972 1:41
75 instead of 65 .020513 1:14
75 instead of 55 .048485 2:55
Using Chart #1 we get the time savings for Chart #2

So is it worth the cost of the ticket and drastically increasing your chances of crashing just to go 75mph instead of 65mph and save 1:14 every 10 miles? Seems sort of futile doesn't it?

So this pretty much shows your wasting fuel but saving time anything over 65 you really start burning fuel. My 350 mile limit a day says I would save 23.3 minutes a day by driving 70 over 65. You stop 2 times to let the wife go at a rest stop in that mileage you`ve lost more than you would have saved.
The ones that have to barrel on thru in the left lane and have to deal with in and out of lanes really are a danger to us all and it`s impossible to maintain any kind of constant speed the left lane anyway with the cowboy truck drivers and the tailgaters. So the calculations will be less. So not worth it.

My problem with the speed is this. I thought my Silverado wasn't shifting into 6th gear. Experimented and found by research the it doesn't shift until around 68mph. I had my top speed at 62 or there abouts. Someone else had noticed this and said the mpg seemed to be almost the same at 62 or 68. You lose by speeding, but then gain by shifting into 6th. I haven't tried 68 for extended time yet, but may try this summer to test it.

I like your math but for me you donít take it far enough. Iím sure that will work good for you and it does when I go with my wife. But when I go to Wyoming with the two guys who work in the shop it doesnít work well. We will be on the road from before 8 am and stop after 11 that night. If we can travel 75 for 10 of those hours that is a hundred miles. We will leave here in western Virginia at 12 or 1 pm and be in Wyoming in under 48 hours. You would take 5 days at 350 miles a day. That is 6 extra days for the trip. You can buy a lot of fuel for that.

Still trying to get my Sailuns replaced under the recall...

I ran the GY G614s for years (around 20k miles) with no issues at all, but went with the 235/85 16 Sailuns this time around.

No problems at all, just the recall...

I can relate completely to the comments regarding speed and tire pressure...
My rig comes in at something under 3,000 per tire loaded (14.500 total weight minus about 3k on the B&W ball). So I'm comfortable with 100 psi and see the pressure go up to around 110-115 under normal conditions.

I run the TST 507 tire monitors and watch the temps and pressures carefully. I'm also of the mind to run about 65 max, usually a bit less. Of course here in the People's Republic of Kalifornia, 55 is the max. which is not a happy place for my Ram and the gearing I have.
No worries I just drop it down to 5th (still O.D.) when needed and it's all good.
I love it when I'm getting passed by some dimwit with a 2500 towing a massive 3 axle toy hauler doing 70 MPH down the Grapevine or elsewhere.
Yeah, I got nothing to prove...but some guys do of course.

I used to go 400 to 450 on days when I pushed it. Getting older (been going for 16 years) and gets harder to travel much over 300 or 350. Since I am retired and have no where to go anyway (LOL) I decided to slow down. Even when young, I would have had a hard time pushing for 12 hours.
