He has a 220 outlet on the porch that he used for an AC that is no longer used. Shouldn't we be able to wire that into a 50 amp plug and use this outlet while we are there? I figured I would be sure to only start up one AC at a time so it is not pulling so much all at once.
Also could I run an extension cord to operate the refrigerator? We have an apartment style 120V fridge or can I use the inverter while connected to the outlet above?
I think this could work but I would like to some opinions and thoughts about this before we do it. All feedback is appreciated. This may or may not be happening next week depending on the response I get here.
Thank you.

It all depends on how it is currently wired. It will need four wires for you to convert over to use on your 120/240 volt split phase RV.
It will need two 120 volt hot legs, a common neutral, and a ground.
Since many of the older 240 volt outlets at house are only going to have 3 wires, (2 hot legs) and either a ground...or a neutral (but not a ground + a neutral).... then you won't be able to easily convert.
Even if you just try to take one of the hot legs from the house 240 volt outlet...you still have to have a ground AND a separate neutral....which both are probably not there presently. You can replace his double pole breaker with a single pole breaker, then rewire using the current 3 wires to make a 30 amp service....and then use a 30 to 50 amp adapter to power up your RV, like you would at a campground with no 50 amp service. It's explained in the link below how to also do this.
Here is a good link to peruse. It explains how to actually adapt things like you may have, and what you will have to do to convert over. It's all explained in the left hand tab links....dependent upon what is currently at the house. Check the appliance link to see first, as well as check out the other tabs which explain it all.

If his outlet has two hot legs, a separate neutral, and a separate ground, you are basically good to go.
