1988 Fleetwood class c airconditioning????

This is my first rv, I have a roof mount, does it have a power cord somewhere I don't know about?

My '04 Fleetwood 'C' works the same way. The power cord storage compartment has a place to plug in the power cord. Then fire up the generator and let it run while driving. I normally don't do that, though. The engine's A/C works for the cockpit and I travel by myself. Once I get to a FHU CG for the night, I let the CG electric take over. It doesn't take very long to cool down.

In my Bigfoot, you plug the power cord into an outlet that has the output from the generator. Then everything works the same as when hooked up to shore power.
