I work on a military base. This requires driving a mile or two at very slow speeds. 15MPH and 25MPH.

I found that in 4th gear (NV 5600 6 speed) the truck will maintain 15 MPH fairly precisely with my foot off the pedal. This is convenient becasue they write tickets for going 18. But is it an efficient way to move the truck?

It's generally not considered a good idea to lug the engine under a load but in this case the computer is really just maintaining idle speed.

Diesel_dave? SLowmover?
