I drove at 62 before and after I was 65. I felt safer and in control at that speed.

X5 - 60-65mph seems a good number for me also. It gets me there with reasonable gas mileage (avg 8.2) and doesn't impede traffic. If I have a good tailwind, I'll bump it up to 70 - 75, If I have a strong headwind, I'll back it down to 55.

Most logical speed is 60 mph. Thats a mile a minute. Makes it easy to calculate time and distance.

Since the F53 is a truck chassis, we used to stay around the truck speed limits. Anything much above 60 used to drop the gas mileage noticeably. The rig's sweet spot was 60, it got noisier much over 65 (mainly wind noise).

Like a lot of posters on this thread we were travelling, not rushing to get somewhere on a specific timetable.

Drive 60 mph keeps the Craze's away, less having to hit the brakes or pass others. slow and steady

On all three of our coaches I have usually held right around 65-67 MPH.

Our first motorhome was a 30' gasser and I put a Gear Vendors unit on it because it was screamin' @ 65 MPH. After I installed the O/D unit I would cruise right @ 65-67 whether flat-towing our Jeep or towing our 24' race trailer heading to the races and the RPM was right around 2600-ish.

Even on our current DP towing our now 26' enclosed trailer or flat-towing our Jeep we still sit right around 65-67.

And I am not retired, my wife and I are 45 and 46 years old respectively, still working full-time. At that speed I am still able to look around and enjoy the scenery without feeling uncomfortable about the speed. We also prefer to get off the interstates and use the 2-lane back roads now that we don't race any longer and enjoy not always taking the shortest route to the destination(s).

65-70 or what ever is safe or when the wife yells at me to slow down. Depends on the road and the wind and the wife.

On interstate or state highways, I will drive based on my RPM. My ideal miles per gallon are between 1700 and 1800 RPMs.this usually means I'm traveling at approximately 65 miles an hour.

Some speeds are restricted by the maximum speed of your towed vehicle. Many only have a 65 mile an hour maximum towed speed

On a long trip I start out at 62 on the cruise. As I get closer to home, the speed usually creeps up to about 64.

Knowing the absolute top speed of your coach is very important to determine what you can safely drive. In the event you have a blow out on one of your front tires you have to be able to put the gas pedal to the floor and accelerate to maintain control of your coach keeping it straight and on the road before your ease off the gas and bring the coach to a safe stop. Most gas coaches won't do better than 72-75 mph tops so 62-65 is a good cruising speed with a little left over for safety.
If you have nothing left to accelerate in a blowout you cannot maintain the coach straight, it will dive in the direction of the blown tire. If you brake immediately when the tire blows you will dive even more violently.
Add pulling a toad to your load and you have an even bigger problem on your hands. If you roll your coach in a crash I hope you will is in order.

Best gas mileage at 58MPH. In no hurry. On the upper East Coast (NE) you can get away with this speed.

Retired, and in no hurry. Did most of my traveling at 60-62 when I first got the RV. Dropped down to 55-56 (2250 rpm) last year on the same 3600 mile round trip and gained 1+ mpg. Doesn't sound like much, but makes a difference in your fuel bill over the long haul. I got passed by a lot of other gas RVs that were doing 70 or 75, but when they were taking the exit to Pilot or Flying J, I carried on down the road, and got passed by them again a couple of hours later. I'm not being critical of those who are in a hurry. Everyone's individual circumstances are different. My choice works for me.
