62/63, reasonable fuel mileage, gets the Allison in 6th gear, and a much more relaxing driving experience than 70.

62 to 65 MPH. I get the best MPG at these speeds.

66-68 mph in 6th gear on the interstate pulling the jeep 1700-1750 rpm ISC 350, 5th gear on 2 lanes 58-62mph 1650-1700 rpm, getting 8mpg eather way.

60 - 65 seems to yield the best mileage. I like to see the mileage over the 9.

Depends on how steep the hill is but the Cruise Control is usually set at 55-60, no more.. If it's over 60 I'm either passing someone or going down a serious hill.

some interesting numbers.

On the US highways and interstates I drive on, going anything less than 70 is just asking to become a hood ornament on a peterbilt.
Even on the 2 lanes, grandmothers in minivans are passing me around corners at those speeds.

70 to 75 for me, in the right hand lane on a 4 lane in the country, the center on a six lane in the city keeps me out of the entrance / exit drama.

My knight gives me better mileage at the higher speed too.
All the way up to 7 running at 75, from 6.0 at 60.

Underneath my house on wheels is an 11-ton Ford truck, so I stick to the truck speed limits.

60 to 63.

60 mph on interstate and maximum of 65 mph on rolling down hills, over 65 mph and the Honda will disintegrate. Poof! At 60 I like to see the gassers puff up their chests as they pass. Too cool.
7 - 8 mpg.

How do their chests look in the mountains?

I just drove the length of California twice at 55 mph---it's the law towing----and they are inforcing the law much to the chagrin of some fellow RV'rs. I found it enjoyable. I avoid freeways as much as practical-----pull out when safe, frequently. Other states 62 is a good speed. Life is good.

I drive the 62-65 range also. I got those number by hanging around these forums and listening to what you gals and fellas with a lot of experience have posted about fuel mileage. I have a 40 footer with a Cat 3126E motor. At 62-65 I am about 1650 rpm and seem to be getting right at 10 mpg when towing a 4,200 toad. I also use Econo mode on the transmission.We are heading out to north Georgia in about 10 days. I am interested to see how the DP operates in the mountains. After Georgia we will to to Charleston, SC for a few days.

WE also drive in the 60 to 65 mile range. Our mh has a 500 cummins but fuel millage is not really the issue. Getting there safe as possible is. I love the USA and all it has to offer , I want to see it all so if I have to cut back some other place to pay for the high fuel then so be it. Also back to what speed we drive, I had a blow out on a steering tire, and it was only 1 year old, and properly inflated thiry minutes earlier. Boy did that get my attention about speed. I was only going about 65 and it was all I could to keep it out of the bar ditch. I and a stocky sort of a fella and it was touch a go to hold on to the steering wheel. I am not comftorable with speed now especially with cars not trucks, blowing by just to cut in front and slow down or turn off!!
