Do you turn off the overdrive?

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

I towed my old pop-up around Canada all summer long on overdrive, Jeep NEVER hunted for gears, but when I had to change the gear oil I wished that I did turn off the overdrive... (Black and lots of metal shavings)

Now when I tow (pop-up or TT), I always turn off the overdrive -
ALWAYS!

Sorry to hear that.

BUT something else was going on.
Even your Jeep Owners Manual states it's OK UNLESS 'frequenting shifting' occurs.
