Space Under Drivers side Bed
Yes the silver box is the Inverter. The black box is an auto transfer relay. I had not thought about putting additional shielding. I have attached the manual for it that I downloaded from Thor owners site. It has safety warnings on it concerning not providing proper ventilation and having it in sufficient space so not sure about encasing it. This box has UL listing and FCC compliance. If your worried I guess you could put a sheet of metal on the underside of the bed platform that would not impede the ventilation. I see no downside from doing that.
