Are there auto-changeover propane regulators (or separate auto-changeover

Is there a reson you can't use the rv ones? *Are you using the same
pressure? *I've not seen any with remote indicators though.

there is ONE BIG reason you can't RV tanks on a generator of any size.
(10Kw) they are Vapor withdraw type tanks and they don't have enough
surface area to allow the propane liquid to boil off into gas, without
freezing up the tank.... duh... anyone who has ever tried it knows
this...

This is true. We run cars on propane over here. The liquid propane
is vapourised in a heat exchange device that draws water from the
coolant jacket of the IC engine. Many are converted from petrol,
there is an annular ring fitted between the carburretor and the inlet
manifold that injects the gas through a ring of holes. Needle jet
controls the gas on the liquid side of the vapouriser device.
