Who's saying it will hurt them? There is just no need in it now days. They make so much power down low there is very few times they have to be run in the higher RPM range.
There is if you need the additional horsepower (rear wheel torque) to get the job done in the time you desire to do it (miles per hour).
The job gets done at 2000 RPM or lower and on occasion short burst of 2500. I've never "had to" go over 2500 rpm to hold a respectable speed and I tow over my listed GCVWR and well beyond the GCVWR of a comparable hp gas truck.
Like I've said before, 2000 rpm is going to be half the wear of 4000 rpm. If you say that today's engines have 0 wear at 4000 rpm then I am getting negative wear at 2000 rpm.
Take a gas truck with 325 hp and hook a high profile 18,000# load to it and take it up and down the road for 100,000 miles holding the posted speed 95% of the time and tell me how she's doin' after the 100,000 miles. Then try it with 25,000#.
I know that most RVers don't pull that kind of weight but this thread is gas verses diesel, right?
LOL!
Getting on the freeway with my five speed, I may wind the Cummins up to 3,000, but towing and pulling hills at speed (55 to 60 on state highways) most of the time not over about 2,300 rpm in 4th (direct drive) with 3.55's moving 19,000#+ with less than 270 hp! Do that with a gaser!
