Running 1 ac unit on 20 amp shore power,

I have a dedicated 20 amp circuit next to where I park my MH when loading and unloading for trips. If only some 12 volt lights, but no frig or water heater on electric were running in the mh, could I run 1 of the roof top ac’ units? Both units are on single 20 amp breakers in the MH and one is 15,000 btu and one is 13,500 btu
.
Thanks in advance

Additional info

I have a 30 amp extension cord with an adapter to 20 amp that I could use.

    A few years ago were driveway camped up in cape cod at a friends house. They had a dedicated 20 amp outlet that I used. I just ran my 50 amo cable to the outlet and used a 50 to 30 reducer which I plugged into a 30 to 110 plug... no regular extension cords and it worked all weekend... all the lights, and 1 AC

    How do I do that?


    should be a circuit breaker on the charger/converter.

    I was just at a friends place and the had a 20 amp socket. I had one of those puck adapters that allowed the 30 cord to plug in. We have one 15k ac, ran wh on gas ( only option ), fridge on gas, did use a Keurig in the am. Would run mw when ac was not. All went well. However when we went to leave the adapter was warm and somewhat melted. So be careful.

    With a short extension cord and nothing else drawing power except led lights, yes.
