Sorry, this messaging is kinda confusing. I’m understand now what you did. A pic of where your external cord is for the 20 amp service would be great. I’m thinking I’ll just wire it in to a breaker and then to an outside cord. Only need to use it when it is super hot outside…like now. Also, yes camping world is no help. Which unit did you go with?

If you have time to talk sometime it would help me a ton. My number is (713) 822-0443 David Rubio

So I am going to add the third ac unit to put 2019 3811ms. I see that you did that. Question 1. Was the wiring for the thermostat there? Does it run to the fan control on the wall like they say? 2. How did you run your extra 20 amp cord? Where does it come into the camper and did you run it straight to breaker box ?
