2500 RPM for 2500 miles

[SandDemon]

All the threads I've seen on the subject say run the snot out of it. 2300 & up is right where you need to be, any lower is considered lugging.

I did the same thing last year driving to the sierra's and back towing my 10K 5er.

No problem at all 70mph @ 2300 RPM #ad

Aside from fuel mileage going in the trash can it is OK.

M1A2, you might be concerned about wearing the motor out!!!!! Oh say in 5 or 6 hundred thousand miles!!! #ad

Nothing wrong with staying out of OD, engaging the cruise control at 2450 rpm's and watching the miles click pass. Kinda like sliced bread along with peanut and jelly. It all goes together.

Should I have any concern with driving/towing on a long trip with the O/D turned off? My 5th wheel is a little over 10K and it pulls a lot better with the O/D off. Any concerns with driving all day in between 2500-2750 RPM? A side from the extra noise that is.

According to the little article my Cummins Power Booster newsletter, the Cummins tech explained that these engine were built and tested to run at constant throttle peak hp for sustained periods of time. The article stated it wouldn't hurt the engine to run at 2500 sustained as that is right around where the hp peak is.
I would think under a load that would also be easier on your automatic.

Don't forget that for those of us with 3500's, 4:10 gears, 2500 rpm is 70 mph with 215-85-16's.

Will not hurt it and as those above stated, you are at about hp peak and ready to ride the torque rise when the hill comes along. #ad
