I echo Loren’s advice. Be sure to buy the service cord rated cable. It has a thick rubber casing to protect the conductor and can be easily adapted to any number of plugs. I just made one with the “twist-lock” plugs from HD. They’re fairly expensive, but really give a good seal (add a little sillicone) to keep dust out. Each plug will probably cost you about $20 each so you may have $50-$60 in the extension cord.
