Thanks. We like to camp off grid in the winter, after pricing RV antifreeze I got to thinking I'm going to be spending a lot of money each time we go, would save some money to just blow out the lines.
I figured there was no reason I couldn't do it this way but wanted to make sure I wasn't missing something.
Biggest issue with just blowing out the lines is that if your system has a low run of pipe you could end up with water in it after blowing out the lines since residual water could drain and collect in that low section, freeze and cause an issue. With that said many do just blow out their lines and the issues seem to be rare if you only do that as long as its a decent blowing out job.
My trailer only takes just over a gal of antifreeze so I just use that, but I don't use the trailer during the winter so I don't do multiple winterizations.
