Cruising Speed

[Jopopsy]

So what's your guy's cruising speed? I used to run at 62 mph (don't as me why I picked this speed, I honestly don't know). I'm planning at running 65 mph this coming year as I feel my Greyhawk w/ its J-Ride + is done really well.

What do you guys run at? Am I playing it too close to the vest? Obviously, weather and road conditions change your cruising speed, but assuming all is well - what are you cruising at?

60-62

I usually travel as close to 65 mph as possible . Sometimes a little higher if passing but I try to stay at 65

The California Highway Patrol can nail you for 10 mph over the 55 mph speed limit if towing. When dragging the Jeep, it's 62 mph. Most states don't limit speeds when towing and are the same as passenger vehicles.

I have read on other forums that 58 is the sweet spot for best gas mileage. The suspension set-up on my GH 31 FS was great out of the factory other than the Helwigs which I adjusted myself. I keep it at 60 to 65 which is fast enough for me and all is well.

60 will get me 23MPG and it still gives me a chance to look around.

It is hard to really pick the best answer as if not towing usually pick the speed of the slow lane between 65 and 73. Towing he jeep 65, towing the one ton dually 63-65 except to pass than the speed goes up. My vote is 63 is very comfortable.

For Seneca owners, max torque is somewhere around 62 mph. I generally run slightly above that - 65 mph and 1800 rpm in 6th gear. At max torque we get the best performance out of the Cummins in terms of longevity and mileage. Don't know where the sweet spot is for the Ford V10.

Freightliner custom chassis division offers classes for class A owners on the engine, trans, and chassis where they explain a lot of that stuff. Wish Freightliner offered that for the M2 chassis RV owners.

Anybody know what the sweet spot is for the E450:

5 Speed -
6 Speed -

As posted earlier I plan on running at 65 when viable as I can discern no real difference between 62 and 65 in my rig. Many times I find my speed creeps up and I have no idea until I look down and see I pushed to 70 !

[Wrascal]

I try to follow the posted speed limit (don't want to impede others) UP TO 65 mph. Passing, maybe 75, but then back down.

I voted "65" because I think that's where I can be found most often. Sometimes I'm up around 70 if conditions are just right, but OTOH, I'm often down around 55 on some roads. Trailer tires used to be the limiting factor for that speed, but now it's my hitch. Tires are GTG, and I'll be upgrading the hitch VERY soon.

I would probably drive 60 mph if it weren't for my lovely wife. She is so used to my lead foot when we don't have a trailer attached that she barely stand going 65 mph, never mind anything slower. I so love that woman lol

My experience so far driving 2 years at 62; there is a parade of vehicles passing me always. My Winnebago handled like complete garbage so I was probably better off driving 55 !! However, as mentioned earlier my Greyhawk is night and day different than that Winnebago.

I run 62mph. My Seneca's just feels "happiest" at that speed. Everything just hums along smoothly.

[MFalcon]

In our 2015 Greyhawk 31 DS, I drive 60MPH and try to keep the RPM's under 2500. I think this give me the best gas mileage (8-10) and she rolls along nicely. I don't care who passes me, the lane if front is usually clear, for a mile or more, by people doing 70+ and my wife and I are in no hurry. Cheers.

At between 60 and 62 I have found that the LML Duramax will have the Allison in 5th gear at about 1,600 RPM which is the peak torque curve and that is where I get the absolute best mileage. That information was with my '11 and I am nearly positive the my '16 will be the same since it is basically the same drivetrain.

[Jopopsy]

In two weeks I'll try cruising at 65. This is where the 6th gear in the 2016s would have come in handy, but it is what it is.

[tom463219]

Do to limitations of my TOAD, my top speed is 65. I set cruise at 62, then if I run up on someone slower, I have a little extra to get around them. Since I drove doubles over the road before I retired. Our speed was set at 62, so Im used to it. Plus you don't hardly ever have to pass anyone.

When towing my 20' enclosed with an Audi Q5 inside (6800# combined) in my Seneca, I run about 64-67, not towing, 73-76. In all honesty... I haven't noticed that big ol cummins giving much of a care either way.... Towing I get about 8.5mpg without it's 11+ :-)
