What the max size inverter

We don't watch TV, use microwave or really anything that uses 110v. I just would like to have some availability for 110v if absolutely necessary.

JMO, but you'd enjoy greatest convenience by wiring an inverter to power the trailer "whole house", meaning set it up so you can plug the trailer's main service cable into the inverter's 120 vac output receptacle. Within the limits of whatever size inverter you choose the trailer then will behave just as it would when plugged into shore power. I probably would have chosen a 600 watt pure sine wave inverter but took advantage of a sale on a 1000 watt version that serves the purpose just fine, will even power a toaster or coffee machine, but most important of all - my wife's hair dryer, albeit on it's low heat setting.
