Your Everest Express will run off either 30 or 50 Amp 120 volt AC. BUT if you plug in with 30 amp yo7 would only be able to run one AC unit and you’d have to d9 some power management ..

There is NO 240 and when you have the box wired for 50 amp or 30 amp make sure that whomever wires up the plug UNDERSTANDS it is t9 be wired for 120 VOLT AC ONLY...

You will only at most be able to get 30 amps total, where with a 50 amp two pole connection you can get 100 amps. This is also looked at as 3600 watts compared to 12,000 watts. If you only have a 15/20 household type outlet, you at most 1800 to 2400 watts, so you are very limited with what you can operate. You can use an adapter, commonly called a dogbone, 50 amp to 30 amp, or even a 50 amp to 15 amp adapter.

Welcome to the forum, and pay very close attention to what Chuck said. This is exceedingly important.

Well once again a 50 amp service and plug is 240 volts at 50 amps each, and one can tap one 240 volt circuit on a standard RV breaker box.

The 30 amp is 120 volts, at 30 amps, it isn't a 240 volt 30 amp, old dryer circuit. The ground blades on the 30 amp plug are different for a dryer and RV. The 240 volt has an L shaped ground.
