Slow Your Roll

And keep in mind that Roehl's speedometers all read 3 miles per hour faster than they are actually traveling. Which means our actual speed will be 58 mph on cruise control. Anybody who uses a GPS will tell you that our speedo's are indicating more than the actual speed.

 

Not all of them, but every Freightliner I drove was that way. Mine's about 2MPH over. I recovered a 9400i and its speedometer actually read 1 less than the current road speed (checked by my GPS and one of those nice roadside radar guns).

 

My truck is about 3 mph less than what the speedo shows. GPS is dead on.

 

Yup, mine was the same way. It read about 2mph slower than it really was.
I am glad I switched companies when I did. Mine is set at 70 mph. I still only run at about 62 or so (old Roehl habit) but it's nice to have the extra power when you need to pass.
