Welcome to Sunline Owners Club and your new coach!
Now to the AC. For "just" the AC unit you need a 20 amp line to "start" the AC. Once it is started then it will run on less amperage, (around 11.5 amps actually) What we call the inrush, a large 37 amp surge for an instant, is the starting problem.
When plugged in the shore line cord it fires up the camper power convertor that can draw a few amps to many amps pending on the charge status of your battery. So if you are plugged into a home 15 amp circuit and the converter is consuming say 3 to 4 amps which is limited draw because your battery is pretty much charged,this then leaves 15 - 4 = 11 amps left over. The AC unit that has the 37 amp inrush starting spike will trip the 15 amp circuit in your house. You might get lucky once or twice but it will not work for long.
When you are plugged into a 30 amp service it can handle that momentary spike of the AC and only if you are not using the HW heater on electric and the fridge. You can sneak by with the fridge on electric but the HW will break the camels back trying to run the entire camper, AC, HW heater and fridge all at once. We use LP gas on the HW when we are in this situation.
If you want to run the AC at home, you can install a 30 amp 120 volt receptacle and run like you do in the camp ground. I have done this and so have many others.
To boondock and run the AC, you need to look for the Yamaha 2400 watt generator Yamaha Inverter EF2400iSHC Home, information
or any other 3,000 watt generator. Or other generator brand that can handle this situation.
The 2,000 watt generators will be working too hard to run the AC and you have to do some electrical thinking to even get them to work. I have a Honda EU2000I and if I create the right conditions I can run my 15,000 BTU generator but nothing else in the camper. Making it not a good long term solution for running AC. We beat the decision to death about the Eu2000I and the the Yamaha 2400 can came out with the Eu200I and if I ever want the AC I would add a 2nd Honda with the parallel hit and run the entire camper. So far this has not yet ever come to be a need.
Hope this helps
