Normal amp draw?

Hello. My first post and looking for information on what the "normal" amp draw should be for a trailer. I'm new to travel trailers, just purchased a Vibe 6504 to use on fishing trips. Aside from an initial issue with a short in the trailer lights, the Vibe has been flawless (so far)..... but, it's just getting to be warm weather and I tried the roof top A/C the other day and it tripped the 20 amp breaker in the house. So, I purchased a KILL-A-WATT and isolated and tested each component. It was obvious why the breaker tripped... my battery recharge pulls 3 amps, the hot water heater pulls 10 amps, the fridge pulls 1 amp and the roof top A/C (fan/compressor) pulls 14 amps. So, 28 amps total. I know the normal service at the camp ground is 30 amps, so it's under that and, I can always run the hot water heater on propane if needed. But, are these numbers in the "normal" range? Thanks in advance for feedback...

Yeah, "normal" electric supply for a TT with one AC is 30 amps, and you'll probably need most of that.

Don't try to use the electric water heater unless you are plugged into 30-amp service. The AC alone will challenge a 20-amp circuit.

It's not hard to add a 30-amp circuit with a 30-amp RV receptacle from the breaker box in your house to near where you park the RV. Then you can run normal stuff in the RV without tripping a breaker. But even with 30-amp service, you can't run the AC, microwave, electric water heater, waffle iron, hair dryer, coffee pot, etc., etc., all at the same time.

All appears normal to me. Including the A/C tripping the house breaker if much of anything else was also operating.

All within spec. And that's even kinda low for the converter, but I guess it's probably a lower amp model.
Don't forget microwave. That's on a 15A circuit.
A/C @ 14A can go up higher. Normal operating can be 16A-18A on hot days.
