Yes. This distinction is key. One needs to understand how a given rig is wired in this regard. Our GWV Legend has a 2800W Outback inverter/charger, and the 120VAC runs THROUGH it. That means that all the sophisticated power-quality checking that the Outback does routinely covers the entire vehicle. For this reason, a full-featured protector such as the Progressive Industries unit is unnecessary. What IS necessary is surge suppression (which, for the record, means: "Protection from high voltage transients" such as those caused by lightning). I am going to add the $50 Leviton unit that you referenced earlier in this thread. It seems ideal for the purpose:
