A lot of people in the south don't use antifreeze. I have never have. I have always drained the lines and then blown them out with an air compressor set to about 30 psi.
Unfortunately, in my first year with this trailer, I learned about the Dometic 310 valve not draining this way as well. My first outing was wet.
I never winterized this last winter because I was camping so often and didn't want to deal with that stupid valve. I just turned the heat on when it was going to freeze. The cost of the extra propane versus the cost of the valve versus the cost of the antifreeze is basically a wash for me in Texas.
