I am want to mount an inverter under the driver's seat and I'm looking for suggestions, solutions, and ideas. It's a small unit, 500 w, roughly 10 x 6 x 4 inches. Someone here must have done something similar. How to attach it, how to ground it, etc. Opinions, ideas, criticisms please. Thanks! .............and, are those small diameter rods that go laterally across the area removable?
