You may be at the limit - Give it a shot - Fell the plugs after the A/C has been running for an hour. If they fell hot. you probably need to re-do the plugs and connectors.

I use mine at home, but I can't run anything else when I run the A/C
2001 Coachmen Mirada (Ford F53 6.8L V10) - Toad 2001 Civic
It won't do MACH 2, but I can get a sandwich and take a pee.

Have run my Coleman Mach unit 13,500 BTU using 12ga 100ft 20 amp circuit. Did not get warm on the outlet or plug end after running all day. Ran TV inside as well. Unit cooled as it should but did not use micro or fridge.

The bottom line is what is the actual voltage with it running. If 104 or lower best to stop it from running and beef something up. Running the unit on too low a voltage will cause overheating and premature failure.
There are 10 types of people in the world.
Those that know binary, and those that don't.
