Gary,
Your only concern is if the air system has moisture in it. Our water and sewer is well protected from cold, but if there is moisture in the air system that magnifies your problems. It is like tipping the first domino. Cold makes leaks show up. Leaks make the aux air compressor run. The compressor delivers moisture to the water traps and beyond if they are not drained regularly.
I would suggest if you can get over a pit on the way up, have someone drain your air tanks, and then you drain the water trap in the steer compartment so you arrive with a dry system.
With a dry air system I don’t anticipate you will have any problems.
