Yeah for acceleration or getting over hills, I allow the RPMs to go above 1500 or more depending on the conditions. It can crawl over shallow or brief hills at 1200, but for longer ones I'll lock out overdrive and let it pull the way it wants. I think our trailer is about 1500 lbs empty.

I generally keep an eye on the side mirror to decide when I'm crossing the thresh hold for ideal running. I'm starting to give serious thought to installing a fuel aneriod from hypermax.
