If you're going to be traveling in temperatures below freezing, either (1) winterize the 5th wheel with RV anti-freeze (food grade propylene glycol), (2) blow out all the water lines with air and pour RV anti-freeze in the p-traps, or (3) plan on running the furnace while traveling to keep the interior and basement above freezing. Be sure your propane tanks are full before leaving. If you're going to be carrying anything in the holding tanks, be sure your tank heaters are turned on. All the above assumes that you will have 12VDC feeding your rig through pin #4 of your tow vehicle's 7-pin Pollak connector to keep the coach batteries from discharging.

There is no need to blow with air. the pink stuff pushes all water out ahead of it or dilutes with it sufficiently to prevent freezing. Works for me in Minnesota at -40.
Since you quoted me, did you notice the numbers and the either/or statement? Option 1 was to winterize with RV antifreeze. Option 2 was to blow out the water lines with air. Option 3 was to run the furnace. I never suggested blowing the lines out with air after winterizing the unit with RV antifreeze.
