Do you turn off the overdrive?

depends on the tow vehicle and the load and the road conditions and whether you are at altitude with a non-turbo motor and how fast you are going and whether the engine seems to be struggling and how hot the engine is getting and . . . .

X3 ... for my vehicle, I do not turn off overdrive. town haul mode mostly takes care of that, and even in mountains areas i've never experienced so-called hunting

tow-haul was designed for a reason.

My rigs are somewhat heavier than a PUP, but I would imagine that the same rules would apply.

If I'm in terrain where the O/D will be turning itself on and off frequently then I shut it off until I'm out of that area. That includes hills with varying grades, stretches of rolling hills and sometimes relatively flat areas where I'm driving into a strong headwind. If I'm on a long grade, the O/D has disengaged then I don't worry about it much. It will just engage again when I'm done with the grade.

Only if tranny starts hunting gears........

If it just downshifts due to grade and then upshifts afterwards no.

I do when I am in the hills but leave on on flat roads...

My POPUP weighs in at 4200lbs

I can tell pretty quick watching RPMs and switch it off... Mine will auto switch out when the drag hits a certain point and that scares the H@@@ out of you haha... It does that on cruis control as well... I'd rather turn it off myself...
