Thanks for posting! I routinely use a small dual-fuel generator on propane for a/c at roadside or parking lot overnight stays when traveling. I carry a dedicated 30# tank that will provide enough power for three nights of use. I have a larger dual-fuel for longer anticipated stays, such as hurricane evacuations on the Texas coast, which runs continuously on non-ethanol gas for the duration of stay. I can also run the a/c on inverter during rest stops and meals when traveling to a destination, utilizing 50% SOC for three hours of run time; the DC-DC charger will then recharge when back underway.
