Lee, how big is the pot? Can you drop it into a "sleeve" That will sorta compact the leaves upwards into a cone shape???
If you are stopping for the night,don't forget to take it inside. The few plant losses I have had from moving have been from cold in the car.
Good luck

I just looked at the width of my butt, and I really think that you can get that plant into the back seat of your car. As Beth says, wrap it so the leaves don't break off. I'd use bubble wrap wound tightly around it and then secured with duct tape. If you do a good job of wrapping, you can even lay the potted plant on its side in the trunk while traveling; just don't let it roll back and forth or it might upchuck some soil. Pineapples are temperature-sensitive, so keep it warm while travelling.

The plant might survive severely trimmed leaves but it will likely pout for a year or two, if not actually going into a terminal decline.

The importation of non-certified plant material is restricted in a number of states. Be sure to check first that your plant will be allowed into and accepted in its new home.

wonder if you could mail it or ship it to yourself at the new place?
