Cruising Speed

[garyspang]

60mph
Does not require constant passing, makes good use of right lane, keeps down noise and saves gas.

About 63-65 max I’m comfortable at 63

65 ... for our Class A 2015 Itasca Meridian 36M diesel towing our 2014 Honda CRV 4 down. No matter what we do we get 9 MPG.

I have a 2018 Alante MH,(About 20,000 loaded) with a Ford F53, V10. I average 8.0 mpg,with a small toad and run between 55 and 60 mph. Mostly rolling hills- Interstate. That seems to be about average - reading the other responses to this message.

when I'm on the interstate I like to the posted speed or traffic flow. If I get in hills I start monitoring my EGT gauge and that really helps on both fuel and engine temperature. I always run a good diesel fuel additive.

So, 65-75 normal cruise, getting around $250 - $300 a day, depending on where I am. I haven't really followed gpm, it is what it is. I just loaded the fuelly app, I might use it this trip.

For nice cruising, I like to settle in behind the FedEx B trains. They seem to have a very similar power to weight ratio to my rig.

Well, FYI: I have a 34ft TT and pull it with a 6.0L Ford Excursion. At 60, I get 12.5 MPG. The last trip was from Florida to SD and back and my average was 12.5 MPG. So, I'm pretty happy.

Been towing either a trailer or vehicles with a Motorhome since 1975 and the best I have ever got was 6 to 9 at 6o to70 mph. That's on a good day going down hill both ways 😄

Fleetwood Excursion 2014
Pull Mini Cooper
9-10 mpg
Follow the flow of traffic

I think gas mileage is dependent on size , gas or diesel, aerodynamics, and speed.
I have a small class A Damon diesel and drove from Alabama to BC Canada 2500 miles and averaged 11.25 was told I could get 12 to 13 so am very happy, as was told like all the other post that well below 10 would be great.

2010 Damon Avanti, 2016 Jeep JK

We drive ~100 RPMs (1550 to 1600 RPM) above max torque which is ~58 MPH.Over 92000 miles we average ~8.6 MPG using the pencil and paper calculations I find it hard to believe 12MPG with a rig you size, weight and Hp.

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 travel just a little slower then the traffic. I leave plenty of room between me and who is in front of. And I enjoy the drive. As far as fuel mileage, I don't care what it is, if I need to be worrying about if it 6 mpg or 7 mpg. I'm driving the wrong vehicle. Don't get me wrong I keep an eye on tire pressure, I don't have to be the first person to the top of the hill, and I simply am not in a hurry.

2011 Thor Challenger towing 2008 Ford Explorer Sport Trac cruising at 65 and getting 7.5 - 8 mph

We shift into 6th gear at 63mph so set the cruise at 63/64 mph and got 10.4 mpUS gal on our recent 2850 mile trip from NEW BRUNSWICK to Asheville NC & back. Lots of hills. Works out to be 12 MP Imperial Gal - pulling our F150

If I travelled at 60mph I wouldn’t get out of 5th gear and be running higher RPMs and presumably get lower mileage.

My Previous Gas MH (GM 8.0l Vortec) got about 5.9mp Imperial Gal towing the same truck.
