Pure sine wave inverter suggestions?

You can take your chances, Kayteg. Since I don’t want any trip ruined by malfunctioning electronic equipment and don’t want the risk of trying to replace anything on the road, I have and will continue to run only PSW inverters. The extra cost is irrelevant to me. I don’t drink from streams, use lower than recommend octane gasoline, run my tires below advised pressure, store perishables above 40 degrees etc.
