Some good stuff in here. If you do move your own tank(s) my favorite way is with a thick ratchet strap or rope wrapped over both shoulders (behind your neck) and going down each of your arms and under the "belly" of the tank. It's a little awkward to walk while you're hugging the tank, but with a person on each end it's no problem.

I didn't see this recommended yet, but have you plastic wrapped your windows and linned the bottoms of your exterior doors with old towels or blankets? Or those cute stuffed-snow-men doing the splits. You can pretty seriously increase your home's insulation factor by taking some of these extra steps. If you have a room that doesn't need the light you can put up whole blankets. Get some good socks and a sweater or two you love and keep that thermostat low :)

Good luck 🤞
