I just had an idea of what "I" would do were I in this situation. Can I get feedback whether that would work, or why it may not ??

Ok, so I have a "transport/quarantine" tub already set up for emergencies. It's "blanket sized". It has a UTH taped to it, which only covers about a third of the bottom of the tub.
All it needs is substrate or paper towels, water bowl, and the thermometer probe attached to the UTH.

Now, my vehicle has a regular power outlet, but you can buy the converters for vehicles that don't. So..with a outlet (needs to be one that handles the voltage) couldn't I simply strap down the tub securely on the passenger seat and plug in the thermostat ? I could have it running in the house for a couple of days beforehand, to make sure everything is nicely balanced and working correctly.
So could I move the tub from the house to the car and plug in the thermostat to keep the temps even ? Perhaps put a thermometer probe into the tub itself with the thermometer sitting on top in easy view to double check temps ?

As long as I keep the temps in the car in normal range (like a house would be) there shouldn't be wild fluctuations?

At each hotel one would only need to unplug the thermostat, move the tub to the hotel room, plug it back in.

I could put the water bowl in at night, and remove it during driving, so there are no spills. For privacy, I could cover part of the tub with a towel. Also to insulate it some.

Wouldn't that work ?

All one would need is a extra tub with a secure lid, a UTH already installed on it. A thermostat to go along with it , and a power converter for the vehicles that don't have regular outlets.

Not "that" big of a deal in exchange for having the snake travel with relative proper temperature throughout, privacy and safety, and in good view (the temps) to check on things.

Thoughts ?
