I'm assuming you're talking about AC power, rather than DC (the battery). All the AC appliances should work; they just may not all work at peak capacity at the same time. The trailer would really rather see 30A.

I've run our 2017 T@G on 20 amp many times. No microwave, but with AC running and small K-cup coffee maker used frequently. I do use a heavy duty power cord to connect to the shore power. It's much less of a hassle to deal with over the 30 amp cord. The only time I've had trouble was with a wimpy GFI breaker on a shore power box one time.
