I'm moving 14 hours away with my RES in tow. I've equipped a pencil-sized plastic box with breathe holes and wrapped the bottom half in tin foil, hand warmers will be taped to the bottom outside under the foil. I purchased moisture pillows (made for hermit crabs) to place inside the box. Does anyone have suggestions on travel? I know to keep him in moist heat in a small container. Any suggestions would be greatly appreciated. Thanks.

That link should cover most issues, if you have any further questions don't be hesitant to ask them
The main issue is keeping them warm and out of drafts if the weather is cool.
Will you be driving all 14 hours in one day or staying overnight someplace? If you're overnighting it, most people bring a small tank to set up in the hotel room-- that is what I did when moving my RES from NY to colorado.
