Rick,Plastar sells a very NICE 5kw Dummy Load using Large Capacitors! Well built and should do the trick even has a fan inside to keep things cooled down!
Or you could buy you a five gallon pail of Mineral oil, take a heating element from a hot water heater, check the impedance, they are NOT all the same. install this down into the Oil, with the proper connector attached and 'Voila' you have a gigantic DUMMY Load.
