Had our previous RV set up the same way but I installed/converted to whole home inverter and installed a Pure Sign inverter without knowing the difference at the time.
I spent the money to use my RV any way I want to and just like (or as close to) all of the conveniences of home.
My only objective is to share the information with others so they are not caught unaware as we were and end up frustrated or burnt to the ground.
I would at least warn my customers of the danger (maybe a sticker or two, they seem fond of those..
).
