One last thing: before leaving on my latest trip I made sure I could
actually change the trailer tire with the tools I carry. Found out I
couldn't break the nuts on the wheel with socket wrench because they were
torqued so tight, so I threw in a breaker bar. Ended up using it in
Parowan, UT to help another pilot fix his DG808C.

Prudent thinking!

Years ago I got into the habit of - upon returning home - removing and
retorquing (by hand, with the [star] wrench[es] in my [appropriate] kit[s])
any lug nut to which an air wrench was applied.

My experience has been that any lug nut receiving an "appropriate torque"
simply does not loosen on its own, while those receiving torque above your
ability to loosen with the technology at hand may not loosen at all...

I've had shops under-torque and over-torque lug nuts.

The former wasn't fun when playing "botched NASCAR pit stop" on a limited
access highway, even as a teenager.

Later, on the road, the latter resulted in serious frustration, and additional
cost in time/bux, while at home I've subsequently twisted fairly new studs to
failure trying to loosen over-tightened lug nuts.

FWIW...
