What is a blanket going to do? LOL! I've left tanks outside on a patio all winter with no problems. Set them up in the spring time with no leakers. As long as no water gets in them and freezes, they will be fine.
Awesome news guys! I got a used 180 today that I only had one friend to help move so there was no way it was making it into my basement. So it's in the garage for now.

Awesome. How do you like your GS500F? I had one a few years ago.
