Ummm.. 30amp TT. I don't think I would want to find out.
But.. microwave in watts? How much to get the magnetron to fire when you hit start? A/C btu's? Lights are LED? TV is 12volt or 110? Is the antenna booster running or are you using a satellite receiver? Sound through the TV or through the audio system? sub-woofer or sound bar? Is the reefer and/or WH cycling? Is the converter in a charge cycle?
See where I'm going with this?
Too many variables.
With a 4000 watt Honda, rated is 3500watts and 29amps. You'll need around 3000w to kick the A/C over and will run around 1500-2000w for a 13.5btu unit. Hit the microwave (650watt).. now your cooking another 1000w. Up to 3000.. TV.. add on another 200w, satellite receiver another 250. Pile on lights and normal trailer power usage... Yes.. I know... lights and trailer appliances are on 12v... Coming from the converter which is drawing on the genny.
Bottom line, IMO, I wouldn't try it with anything less than a 4000watt and I wouldn't give you odds if you could get just the A/C, microwave, and normal "idle" power consumption throughout the rig running at the same time without tripping/blowing a fuse.
