The first thing you need to do is do an energy audit and find out where your losses are really coming from.
Go buy a clamp-on DC amp meter similar to this one:
Uni-T DC Amp Meter
Turn everything off on your trailer, then clamp onto one of the main wires coming out of your battery bank. Take a measurement, this will give you your parasitic draw. Then turn things on, one by one, and see what the current draw is.
In general, it is not good to connect anything that draws a lot of current (coffee maker, microwave, hair dryer, electric water heater, etc) to the inverter as there is a 10X increase in current from the batteries. For example, if a coffee maker draws 10amps (quite possible) it will draw 100 amps from you battery.
Good luck and have fun.
