I picked up my 1st travel trailer. I want to be able to run the A/C, TV and use appliances without any issues. The A/C is 13,500 BTU. The trailer is a 2016 Jayco Jay Flight SLX 267BHSW.
I have a Champion 3100 watt inverter generator, it has no problem running my 13,500btu AC and TV at the same time, I haven't tried the microwave with the AC running though. On eco mode it isn't much louder than my friends Yamaha 2000i, but when it is cranked up running the AC it is noticeably louder although I can't hear it inside with the AC on. Weighs around 90 lbs and has wheels on one end and a flip up handle so moving it around isn't too bad once I get it out of the truck.
