so last winter i had a little ro that i kept in the house, but i now have a bigger ro that has 2 20 inch membranes that is in my van, last winter i just used to put a heater on in the morning to unthaw things before i went work, now im worried because i have the membranes in van and cant do it.
so do the jackets you buy to put over them keep them from freezing?? or do you need to also put a heater on in there through the night?
really dont like the idea of having a heater on in the van through night in case it catches fire
