Do you know what chassis the Bounder is built on (Spartan, Freightliner, etc.)? There should be a power compartment where you can find twelve volts - different chassis manufacturers do it differently. You should be able to route a cable from the power source under the coach to a position directly under the driver's seat, drill a hole through the floor. You just need one 12v cable and one ground cable, so a 1/2" hole should work. Powered flexsteel seat pedestals are usually a direct swap-out with the non-powered pedestal. The biggest obstacle you may face is getting to the nuts that are under the coach connecting the pedestal to the floor. If your coach has an under coating, those nuts are buried in it.
