Getting the Keystone Cougar Travel Trailer Ready for Winter (No RV Antifreeze)

How to winterize your RV without using RV antifreeze in the fresh water piping or tank. I use compressed air to blow all the water from the pipes and get my camper ready for the long Alaskan winter. This keeps antifreeze out of the fresh water supply so there is no flushing the system next spring.
We also winterize the traps with RV antifreeze and pull the batteries and put them on a trickle charge. I also go over the location of the black and gray water valves.

I use an air chuck fittings with a hose connector to attach the air compressor hose to the city water connection of the camper.
