If or when your engine develops an idle miss that no one can figure out,
remember those plugs....

I tow a pop-up behind my TJ and use overdrive (5th gear) most of the
time. I only upshift when there's a slight grade or the engine acts
like it's starting to lug a bit. Your XJ's 4.0L is a real torque-monster
so until you get onto a grade, it should be fine in OD.

Most automatics are not as forgiving about towing in OD as a manual
and it should be mostly avoided in a XJ. Even more so if tires are
bigger than stock. BTW, OD on a automatic is a taller ratio than OD
on your manual is too and unlike your manual, the different clutch is
used in OD which is not a strong as drive clutch.
