Anytime an increase in throttle does not result in an increase in speed or
the engine is losing speed with significant throttle it is being lugged. And
this happens at any RPM. If you going up a hill and losing speed you are
lugging the engine. How far down your foot is determines how much.

At 3k rpm@  60 mph is not considered lugging and I don't drive with the foot
to the floor at lower rpm as well. I also don't lug the engine elsewhere in
any of the gears unless in first gear starting from a stop!

Yes slowing down the engine means less power. It was geared the way it was
for a number of reasons. You just need to spend more time in third to
compensate. Not only are you making less power but you are increasing stress
on the engine. Unlike a real truck engine it really is not designed to be
continuously lugged. The increased torque requirement means higher stress
and cylinder pressures which increase heat and NOx emissions. I would invest
in the later-turbo diesel engine for the increased power and strength. The
pistons and crank are not the only differences.

Hi Volks!! Took my first trip with the air cooled tranny in Velma and loving
the rpm change at 60-65...
