Make SURE you add air as you go North again (remember cold tires in the morning before you leave). This is why carrying a GOOD compressor, 25 feet of hose and an air chuck is so important when Snowbirding.
I have found that "most" battery powered air compressors don't have the capacity to inflate a truck tire to 80 PSI. There is an awesome thread here on the merits of several popular brands that will fit in a trailer's compartments.
