Inverter usage while underway

I don't see where "Mr Wizard" owes you an apology. People are just trying to tell you that you can do what you want, but it's not the best approach. We didn't all just show up yesterday and start working on RV's. Many here would be better than half the techs in the country if they didn't have other jobs.

Just to answer your question, in 35 years of RVing with units that use propane, particularly refers, I've never shut my propane off from the time I leave the house until I get home, including fueling. Take some time to read and understand propane systems.
