RE: 110v AC Safety
While on this subject another tip.  Carry one of those little plug in
testers and check the line you are about to plug into your van BEFORE
connecting it!  I test every time now after burning up my battery charger
at a campground in Oregon while connected to a bad power outlet.
BTW, since using the tester I've never run into a problem connection but
one will surely come up some day.
