I usually drive about 60 on interstates. Seems a good compromise between speed and gas mileage. Pretty close to the posted speed limit on other roads with lower speed limits.

We tow a vehicle so we practice 5 mph over the posted speed limit for towing which varies from state to state. But our limit is 70mph regardless.

What's the hurry? It allows for relaxing mornings and evenings when the day's drive is done in less time. With limited vacation time and 5000 miles of driving to accomplish, something gives.....fuel economy. Still with our driving practices, our vacation average is a decent 9.2 mpg because of the B+ aerodynamics with angled wing walls, a lower roof, and only 9200 pounds of motor home.

Head wind is less influential.

If I ever retire having more time, then we would surely slow down to a max of 60mph. I look forward to that day.

We go the speed limit, but never exceeding 60 MPH if the speed limit is higher. We're just not in a hurry.

60 MPH is just right, Stay to the far right (Slow lane) If on a 3 lane hwy you should still stay right and move to the middle lane only to allow for on coming traffic to merge then move back to the right, Whatever you do don't never hold up a big Truck, He might have someone's RV parts inside the trailer and needs to deliver on time.[emoticon]

When gas prices were under $2 I passed cars all the time --- now I let them pass me. These days I tend to stay in the slow lane and sick to around 55.

I travel the speed limit, no matter what it is. I feel that slow moving vehicles are a hazard to others traveling the speed limit.

I agree, I feel safer moving at the speed limit or as close as possible. But I let car traffic pass wherever they can. Our rig has no problem pushing 75 but I prefer 65. Our limits here are 65 because we are urban. Up on 70 cross country it is 75. Maybe 10 south is 75 too now that I think of it.
I'd like to take the RV to Colorado this year. It will be interesting to see how it performs on the major highways and in the mountains. Going north to Flagstaff we tend to get into the slow lane and go up with the trucks.

We run at 55-60 MPH, maximum, at all times (if it's safe to travel that fast) on highways and freeways ... to get good gas mileage and stay more relaxed.

The OP stated:

I put it at 65 and it seemed to hum along nicely but the V10 was really roaring at times.


For those of us using a Ford V10 based Class C, note that how fast the V10 is spinning for any given speed depends upon whether you have the E350 or E450 chassis. The differentials on these two chassis have different ratios. The E450's differential is geared lower, so the engine revs higher at any speed than will the engine in an E350. Traveling a bit slower with an E450 chassis than you would with an E350 chassis will keep engine noise a bit less in an E450.

I helped this situation out on our E450 Class C by recently installing a set of tires on it with a larger diameter than what it came with stock.

55 to 65 and mostly 60 gets us the best mpg, stay in the middle lane as much as possible to allow others to pass.

With gas prices the way they are and will be getting worse - upwards to $5.00/gallon we'll keep our cruise control on 55-60!!!! We'll only travel 200-250 miles at a time so - no rush!!!! I'm part Native American and I always say

Hey! That's my line.
