Yep, that's the one we have for dry camping. I bought the 115v ones for upfront because they work do much better than the 12v, and can run off the inverter when the engines running. As far as the O2 fans, they do not run very long on 6 new batteries, but the come with a cord so you can hook them into you 12v house batteries. Then they will run all night or all day.
