I have 2 rigmaster APUs. One is complete with blower motor, hoses, cords, and control panel. The other is just the APU, but it's in better shape. Figured between the 2 could make a complete one. Was told both were running when taken off. Never mounted them, or tested them. But both turn freely. I have a $1000 between the 2. Asking $500 for the pair.
