3 position Transfer Switch
I have an older class A RV, I was thinking about installing an inverter but wasn't exactly sure on the wiring. To me the easiest way if it's even available would be to have a 3 position transfer s...

wiring two transfer switches off the generator doesn't seem overly complicated.
Generator turns on and kicks the inverter off and same for the 1st transfer switch. Does the transfer switch take priority from shore power?
I would have to turn the breaker off for the battery charger.
A transfer switch basically takes two inputs (A and B, which can be wired to shore power and a generator). One input, usually A, is the default. This is where it will connect to for power if there isn't any stable power on B. When power appears on the B side and it's determined to be of proper voltage and stable, the transfer switch will disconnect from the A inputs and connect to the B inputs. If power is lost the transfer switch will return to the default position, and in this case attempt to get shore power.
I suppose you could wire two transfer switches up in series to be able to take power from three different sources, but that seems overly complicated and expensive. There has to be easier ways to achieve your goal since most RVs with inverters do that akready. In my RV I have an inverter switch that will supply power to a couple of 110v outlets when I'm not on shore power or running the generator.
