Travel Speed

You must have one heck of a fuel flow meter installed.

If everyone drove slower, we would all save money, be safer, and conserve fuel.

That may have been true during the national 55 speed limit, when autos and trucks were geared to the "sweet spot" of fuel economy at 55-60 mph, but today, they're geared for higher speeds, with overdrive transmissions, full lock-up torque converters and computer-controlled shift points. That all equals out to "best" fuel economy at almost any speed you might drive.

Not so sure about the "safer" part, what with a big wind-catching wall back there to get blown over, or start whipping around to jack-knife you, but that's another issue.

That being said, YOU are still the operator, and may drive any legal speed you feel safe at. I have a mental saying when overtaken by somebody that seems to be in one heck of a hurry......"Speed on....hell's only half full"

Drive like hell, you'll get there!

We run 60 to 65 in the right lane.

Coach is happy running that speed and much more comfortable than driving 70+.

 

[vermontcc]

65 max for us. This is a sweet spot for the Ford V10 with overdrive transmission.

 

[Scooterfan]

I usually put the cruise control on 65, but if there's any cross wind(s) I find 62 is the mph that is most controllable. Not sure how that all changes now that we purchased a TOAD. A FIAT 500 so it's light (2,200lbs). Not expecting too much change in driving speeds but I won't know until I get on the road with her. Drive at a comfortable speed for you but stay in the right lane unless you are passing. JMHO...blessings

 

[Crazydog]

Drive the limit!..Anything slower will create problems for others and potentially cause an accident! Is that worth saving a buck or two?

The OP was talking about being on an interstate. Every interstate in the U.S. has at least 2 lanes in each direction.
Driving under the speed limit in the right lane will not hinder anyone. They are free to pass at anytime.
I set my personal speed limit at 65mph if conditions are good whether I'm towing our 25' TT or our 40' 5th wheel and have never caused a slowdown behind us in over 40+ years.

 

[sanda]

65 max for us. Mainly for safety and not fuel mileage. Blow a tire out at 75 is more apt to put you in the ditch

Overdrive!
The importance of using your tow/haul setting is evidently understated. Won't say more unless pressured.

Are you implying that OD does not work in Tow Mode?? It sure does on my 2011 F53 and the owner's manual verifies. At about 60 MPH on a level road with minimal wind we cruise at just over 2000 RPM in OD in TM

I would not imply that! In tow haul mode my truck stays out of OD. if I were driving your f53 the same would be the standard. I have tested this with the ers.

Though I miss typed 55mpg above, you know I ment 55mph. TOW/HAUL is on when I tow or (haul) loads close to capacity. I can lock out OD using the ers but the only reason I would have to do that was if I was to brake my 55 rule.

So yes! What OD?

That is a pretty broad, all inclusive answer. If this is the case, stay away from desolate area like west Texas. The speed limit is 80.
I drive at 65 and that seems to be around the best MPG and not be a big hinderance on the roadway.

Happy Glamping!

I can go 80 if need be, but prefer not to. I'd likely be @ 70-75 in that case!
If I had the time or inclination, I'd, just for you, spell out all 50-100 scenarios that might ever occur!
I can camp or glamp just as easy as I wish.

What is "ers"? The owners manual says the tow/haul improves the operation of the transmission and all gear ranges are available. That means, and I know for a fact, OD works in tow mode. So yes!! That OD.

This could be a difference of definitions, what is OD?
In the “old days” OD used to be another gear range but now it seems to be, in the age of automatics, the locking of the torque converter.
So tow mode can be using all gear ranges, just avoiding the torque converter locking to prevent damage from slippage.
