How can I run both air conditioners?

Check out safe RV power. This transfer switch is designed to do exactly what you want. I just installed one on my fiver



Safe RV power transfer switch

WyoTraveler, could you give me some kind of diagram and a suggestion for which transfer switch to buy? Thanks, Miles

Fleetwood had the same arrangement in 89. I added a heavy duty transfer switch in the generator compartment where power comes off the generator for the other side of the line. I ran a 20 amp line to the power source. With the 20 and 30 amp plugs the RV still thinks it is on the generator. Fairly easy mod.

Most RVs that let you run both are 50 amp. The thing about 30 vs. 50 amp is that a 30 amp service is a single 30 amp circuit. 50 amp is actually 2-50 amp circuits for a total of 100 amps. My older Dometics draw about 18 amps each. No way to run both on a 30 amps hookup.

30 amp RV? If you rewire both to operate off the 30a panel you will really be maxed out. Also a 30a panel is limited to five branch circuits so something else may need to share such as electric water heat and microwave.

Otherwise you need to pull wire from the switch to the panel to get power to both. Or as said above to break out power from one of the units to a separate plug.

Add an auxiliary shore power cord for the air conditioner you use the least often.
