I get better than that non towing and hand calculated with ease on my 04 4x4. Is that the 09 bighorn or the 12 dually megacab? If you get that hand calculated in your dually megacab, then you got a good truck.

Thats about the same tach RPM's and MPG I get at that speed, also non-towing.

Nice to see it there though.

My 2005 Dodge 5.9 2500 Ram would get me consistantly 99.9 mpg coasting down hill. LOL

On I-95 wasn't towing.......

Mine is a 7.4L with 4.1's and LT265/75R16E's. So the speedo is off by
about 6% so the that 64 MPH is actually 68.x MPH

Notice the newer dash tach's no longer have a red line...computer
controls you life these days...

Also, since there are speed limits on all of our public roads that are
enforced...our OEM dash speedo's are actually pretty accurate because
of the fact the LEO's enforce posted speed limits. They can't have
the defense say their speedo is a piece of $#@%

What is the light on the lower right of the speedo? Not familiar with the Ram cluster.

Looks like your ABS light is on.

If I reset the lie-o-meter on the '08 F-450 I drive while at speed it will read 99.9 mpg until I step on the go pedal.

That looks like the light for when the exhaust brake is on...kind of hard to tell.

Going 60mph on I-95 is a good way to get read ended.
