Hmmm

Two points:

I RV, therefore MPG is not my first concern. This was never about miles per gallon. How can it be when you plop a ďhomeĒ on top of an unsuspecting truck or trailer bed? Both are inherently inefficient from a fuel economy perspective. Speed and itís impact on fuel efficiency was not the primary consideration for us and Iíll guess for more than a few RVers.

As a group, letís never confuse the way we want to travel with an economic justification for why we travel this way.

Second, if you want to drive that slow, please please do it in the right lane and never come into the left lane. You tootle along behind the corporate trucks, speed governed to 65 MPH because of the lawyers and the actuaries.

I have somewhere I want to be and Iím willing to pay a few dollars more get there my way.

And yes, Sinatra is on our road trip play list

Many years ago I was in a truck stop having a coffee when this guy walks and brags " I had a great run from ...today, cut ten minutes off my best time" An older gentleman spoke up and asked, " and what did you do with the ten minutes?" The response from the crowd was priceless.

Friends, this is not a race, there are no prizes.
Enjoy your trip, getting there is half the fun.

Dutchstar towing a Silverado....6.7mpg at 64 always. Unless of course there is a big hill coming, then I usually floor it up to 67.

My Winnebago Vista (V10 Ford gasser) gets 8.2 at the best. Pulling our Jeep it drops to 6.5. It depends a lot on winds and hills. We try to maintain 60 most of the time, but I think for max mileage 55 works better.

We cruise in our Renegade at about 62-65, sometimes 70 on wide open highways in Texas. Of course typically lower cruise speed at night, in rain, more traffic, etc. We get about 7.5-8mpg depending on hills and whether we're running the generator.

We seem to consistently get 6.5-7.0 mpg depending on speed, terrain, wind, etc.

(flat ground, long runs, little wind)
55 mph = 7.0
60 mph = 6.8
65 mph = 6.5

Add hills, short runs, wind........ knock 1.0 mpg off those numbers.

Alway pulling the toad, 55,000 lbs.

Safe travels,
Mark

and that's fine, as long as your tires are rated for that speed and doesn't come apart and fly through my windshield

Per year, there's a limited amount of money that I can spend on RVing. Obviously, most of us here have to "budget" our money. Traveling by motorhome, towing our GMC 4x4 Envoy, is the only way I travel, it's the ONLY way to go (comfort and convenience and safety). Yearly, if I exceed the yearly RVing budget, I quit until next year. But, I cruise at 65 because it makes sense in other ways (it's safer, for me). I "profile" other drivers, I'm the best driver I know.

You are from Ontario Canada and I assume the previous owner was Canadian also. Most of the responses are coming from US based RVíers quoting anywhere between 7 and 9 mpg. Remember the Canadian Imperial gallon is 1.2 times larger than the US Gallon. He was most likely quoting miles to the imperial gallon.

I travel at about 60mph because the previous owner said that was the best speed for fuel economy and he would average 12 MPG on a trip.

On my last trip of just under 500 miles, I tried to cruise at 60mph and at the end I got 8.2 MPG. Now mind you that was through the hills in the Finger Lakes, but still getting almost half of what he did.

Unfortunately, I can't ask him any questions because he passed away just after selling me the rig.

So I will be very appreciative of all what you have to say on this subject.

Thank you

I've been living on the cheap for 20 years. When it comes to fuel, the only way to save $$$ is to slow down. Most moho's have a certain speed that they get the best mileage. Most of them it is at 50 mph or slightly above or below. My friends get the same as you, I get 11 mpg towing. I drive at 50 mph in 5th gear on a 6 speed tranny, my coach is 29k lbs. That is the best speed for this coach. Driving slower in traffic is tough, but after 10k miles or so you get use to it.

Safety???? blow outs at 50 are controllable, at 75 they are not. Turn on your headlights for safety. Tires, brakes, wheel bearings and many other chassis parts last longer when you slow down and the moho is easier to control.... The top speed rating for most moho tires is??? 75 mph at 80 degrees ambient.

Sure, I let it drift when I'm going down a hill but set the cruise at 50 when on anything else. My cars I drive at or above the speed limit. Think of it this way, the slower you drive the further you will be able to go per dollar. On 2 lane highways, it is easier for big rigs to pass you when you drive 50 than when you drive 60. When they pass I slow down for them to help them pass.... Oh sure, every once in a couple of years you get one that is stupid and hasn't figured out what is going on but such is the nature of newbies.... No matter how fast your drive, there will always be some fool who will pull out to pass, why not make it easier for them?

Speed costs money....

I find your post extremely confusing. You talk about the safety of your tires, but are completely blind to the unbelievable hazard you create by driving 20 mph below the speed limit, which in most cases will be 25 mph slower than the rest of the traffic. I realize you do not care about the traffic behind you as long as you are not the one who is rearended. Who cares about anyone else, right?

The speed limit, as the word limit implies, is the maximum limit, not the speed your obligated to go.

If your driving above the posted Minimum limit, your OK.
It is not unsafe to drive 50 MPH in a 70 MPH area, even if others are exceding that limit.
Bad behavior doesn't justifie more of the same.

What becomes unsafe, to the faster drivers, is them not judging your speed and waiting to pass properly.

How often have you crashed into vehicles traveling slower then you ?

In mountain driving it is unavoidable for all vehicles to maintain the speed you choose to drive. Drivers just need to be aware of others on the road.

Do you have any stats on this unbelievable hazard ?

If you are worried about MPG on your motorhome you can’t afford to drive a motorhome.That was told to me by the Salesman who sold me my First motorhome in 1975 . And it is still true today....Enjoy the journey..Not the MPG...
