I agree the new insulated doors that they make today are far superior to the old heavy wooden ones from years ago. I guess I was assuming that the doors were the newer type.
It still wouldn't hurt to get a bid on the cost of moving it. Ask lots of questions about raising power wires, crossing bridges, cost per mile etc. You never know, this deal might not work out, but another one that is better might come along. In that case, you would already have a rough idea of moving costs that would be involved.
It never hurts to know too much, just in case that great deal comes along.
