When the winter finally relented with the under freezing temperatures I started getting our camper ready for the camping season. I had three different things I needed to do to get the camper ready to go for the 2018 season. First I had to make sure all of the devices that ran on batteries, most importantly smoke detectors, had new batteries. Second I wanted to make sure the water system had all of the RV antifreeze rinsed out. Finally I sanitized all of the water supply lines and fresh water tank. This video shows the batteries and line flush. I will post the sanitizing video in a few weeks.
