Thanks for your input Walt, always very much appreciated.

Prior to posting I had resolved that I was going to need to change transmission and rear axle ratios. I was/am considering various combos.

The reason I specified in my post "Highway empty" was,I had already resolved that towing, hauling would need a different power band.

I had already spent some time with optional ratio changes on paper so "rpm highway at 70 mph" opinions were and are appreciated. I gotta admit "more is always welcome" especially when coming from some one with tons of knowledge and experience like Walt.

So here is where I am heading,....

Considering my retirement budget, I am considering these affordable changes,......

#.-- 70 mph @ 2380 highway empty, while still being able to down shift to a towing mode in direct drive which gives me ,...

#.-- 60 mph @ 2950 towing my 7200# RV with direct one to one drive.

I felt these two RPM's compromise quite well.? Gordo
