I have a travel tub for each of mine <only have 2>, a portable space heater and a small portable evaporative cooler should I need it. I also have a snake preparedness kit, very easy to grab on the way out. Has back up hides, substrate, spare temp gun and gauges. We are lucky in that we have a toy hauler that is always packed and ready to go with generator, water, towels etc to gather everyone up in including all 8 of our pets and get out. On the bright side, this time of year we don't have a lot to worry about as far as cold temps.
I wish you luck out there, I'm in the AV so am very familiar with your circumstances right now. Had the station fire two years ago and just finished the massive one a few weeks ago. One evacuation, one avoided barely.
