Appliance Amp Draw

I apologize in advance if this is a redundant post but is there a list somewhere of appliance amp draws for the pods?

I'm new and trying to learn the abc's of inverters and converters and all that without bogging myself down with too much information. I've seen some stuff online that's helpful but what does that big mother AC unit draw for amps? 15 I'm guessing?

I've learned running the house battery too low reduces the life. That was helpful. Just got a 90 watt solar panel to hopefully keep from pulling battery too low.

Lastly, how critical is it to have a voltage tester/surge protector? Anyone have bad experiences with campground voltages? We boondock mostly but I'd love to hear your stories.
