Hi, SG!
What a conundrum. We love our
plants and hate to leave them behind but will they survive the journey?
I would say that they could survive the trip provided once you get to the Soutwest the interior of the truck doesn't get too hot.
If you're renting the truck and moving yourself make sure you have access to them so you can check them over. If your move is being done by a transfer company I'm not sure they'd survive as I'm sure the driver will not be able to check on them. I guess my biggest concern would be extreme temperature changes, hot or cold, inside the truck and I don't know if there's anything you can do about that.
