I was just making that point to someone earlier this evening. Anyway, it matters not what others think or do, 60-65 mph is all I'm going to do.

Hi, there are a few ways to think about your speed especially while towing. Speed limit is 55 MPH in California, but the traffic, for those who are supposed to do 55 MPH, usually are doing about 65 MPH. And that is what I usually do. Occasionally I will hit 70 MPH, mostly in other states, but no faster. Then there is the cost factor. How much more fuel am I burning? What will my speeding ticket cost me? How much will my insurance company increase my policy price when they find out about the speeding tickets? At 80+ MPH versus 70- MPH, how long will it take me to stop this thing?, How many times will it roll if I lose control of it?, And how many more people will, or could be, hurt at the higher speeds?

I live in California where, as noted we have a 55 mph limit for trucks and trailers, and pull trailers at 55-62 mph. We get about 14 mpg on the flats.
This seems like a fine way to travel, and the miles just click by. I'm not the slowest person on the road, since we maintain that speed on hills. I've done a 900 mile day pulling the trailer (17 hours); I was definitely ready to stop driving by then.

Some quick calculations:

Our truck weighs 7400 lbs w/ us aboard; the airstream is prob. close to 4750 lbs... at 60 mph, that's 1.47 million foot lbs of energy, or about 600 30-06 rifle bullets. At 80 mph, it's 2.6 million foot lbs - nearly twice as much. As I mentioned, we get 14 mpg at 60 mph... that's 4.29 gallons/hr, or about 61 hp. To drive 80 mph would take about 145 hp; we'd be burning about 10 gallons/hr and getting (obviously) 8 mpg.

So, at say $4.00 gal for diesel, traveling 200 miles at 60 mph costs
$57.14 and takes 3 hours, 20 minutes. At 80 mph, that number is $100 and it takes 2 hours, 30 minutes. That 50 minutes costs you $42 in increased fuel consumption!

Note also that all but the simplest stability equations for trailers have velocity-related terms - in other words, the faster you go, the more likely you are to have sway problems.

Slow down, and be safer, spend less, and arrive less stressed at your destination.

- Bart

We tend to pull Lucy at around 65mph, conditions permitting. She very often slips up into the 70/75mph range on the open Interstate. We have now pulled Lucy 90,000 miles with two gasoline Suburbans and now a diesel pick-up. I have not found any appreciable fuel mileage benefit at lower speeds.

On our current tour of Florida, I did a mileage comparison between pulling at 60mph and at 70mph. There was only a .2mpg difference.

What mileage are you getting?

I have always enjoyed and owned Corvettes or English roadsters and of coarse Harley Davidsons and other cop magnets. After my share of speeding tickets I learned to never drive in the left lane and always make sure somebody is going faster than I am. No tickets in over thirty years.

When I was working going on vacation meant driving straight through leaving Friday night after work. Many trips from L.A. to Washington State. Vacations were spent somewhere rather than getting there and back.

In 1986 I bought the first of my antique automobiles, a 1926 Model T Ford. I suddenly learned the joy of travel at 45 mph. Our first tour was three weeks after we bought the Model T. It took a week and was about 800 miles from L.A. to Ensenada to San Felipe to Mexicali to San Diego and back to L.A. We traveled with about twenty other Model T's and consumed way too many Margaritas. We had a ball. Since then we have driven over 30,000 miles in a Model T and have over a dozen antique cars out in the shop. You would be amazed how much more you see when you slow down a bit.

Now that I'm retired long days driving are a thing of the past. I drive at the speed limit or 2 or 3 miles over and stay to the right except to pass. In the Airstream 63 to 65 mph is fine. I do gain a little speed as we get near the campground especially if we are a little late and I'm getting hungry.

No doubt age, family and job status and many other things enter into the picture but travel in the slow lane has a lot going for it.

Cheers, Dan

It seams you are not alone in having a lead foot. I have had the trailer for 3 yrs. now, and now I am just getting used to going slower. I think you will find as I have, it's not what you will save in fuel, but how your stress level will be lowered. With me, when in fast mood, I tend to Really get more stressed with the trailer back there. Now, when we reach our destination, I feel no stress. Much better vacation that way!!

When traveling without a trailer behind me I will drive at 75 to 80 mph and be worn slick and stressed at the end of a 500 mile day. I pull the AS at 58 - 62 mph and arrive at my destination feeling minimal stress and ready for action.

Now I just need to work on transferring my trailer towing driving habits to my non-trailer towing driving habits. Old habits are hard to break.

On a side note, I have been pulling camping trailers with ST tires at less than 65 mph since my first trailer in 1985 and have never had a tire failure. I do change out tires based on age (5 years), side wall cracking, or tread wear.

I couldn't do it when working either, but now a 550 mile trip would take me 3 or 4 days with detours for exploring.
I had to hurry so much at work that I had to force myself to slow down on my time. For me, the destination is the excuse for going, and I sometimes never reach the planned destination because the journey is so much more interesting.
Try setting a close destination and take your time getting there. You may like it. Or, then again, you may not.

Exactly. It's about the journey, when you have the privilege to get to that point in your life.

However, when one is still working, or otherwise has a limited time to travel, the hell-bent-for-leather mode gets you where you're going faster.

Staying off the interstates forces one to drive more slowly, as there are farm vehicles, small animals and stop signs to slow you.

When I'm driving a Government vehicle on the clock, I'm required, by regulation, to limit my travel to 350 miles per day, EXCEPT if that leaves me within 75 miles of my final destination, in which case I'm allowed to push on the rest of the way. So, maximum one-day drive on the clock is 425 miles. That's regardless of posted speed limits. We're also required to take a 15-minute break (or switch drivers) every two hours.

I don't always hold to that when driving on my own time. I'll do 750 miles in a single day when traveling to visit my family, but I still observe the 15-minute break rule, and add at least a two-hour break after the first 350 miles. There's a line from the short-lived and mostly-forgettable Babylon 5 spinoff, Crusade, where Galen tells Captain Gideon, "Expect me when you see me." That's what I tell my parents when I plan a visit. Makes for a much more relaxing drive!

As soon as I go off the clock at the end of a work day, I go on "Sanity Savings Time" where an hour is only as long or as short as it needs to be.

The mileage trials on this trip were done while pulling with the Suburban (gas) on flat terrain for two separate 40 mile runs. The 60 mph run netted 10.3 mpg. The 70 mph run got 10.1 mpg. These figures were determined using the Suburban's Driver Information Center.

The slower we go, the more people get to pass us, and many give us a thumbs up as they pass. The joy I get from their admiring stares makes it totally worth slowing down a bit.
