Had to chuckle as I read the OP "is in the film industry" and "plug in many hairdryers, curling irons..." as that kind of describes our family.
My son and son in law are in the film/tv industry, and my wife is a hairdresser, who won't camp unless she can plug in her massive industrial size hair dryer and curling irons. I did finally convince her that she can only plug in 1 piece of equipment at a time (or rather, the generator screaming an agonizing death rattle before shutting down every time the hair dryer kicked into afterburner did).
