Running trailer from tow vehicle inverter

Yes, but you have to disconnect the converter, otherwise you effectively create a short circuit.

There's no need to "disconnect" the converter but simply turn it off and no, leaving it on while using an inverter to power the trailer "whole house" doesn't create a short circuit but merely a closed loop. There's no reason this can't be done but one wants to also make sure the fridge is forced to gas, any water heater electric heating element is turned off, along with anything else drawing 120 vac that you don't want running when using the inverter.
