Time to review the full strategy.
Do you camp in the sun ever? 200+ watts solar would reduce generator time for charging a battery and maybe put the generator out of business.
Do you really need the microwave or air conditioner to run on generator? MW is convenient and still all can be heated on the stove or oven. I honestly look for hookups if the air is needed.
How many batteries do you have and what converter is doing the charging? Many OEM converters just trickle charge at 13.6 volts. You could cut your generator time in half or better upgrading the converter. More battery can also make generator time more productive.
LED lights are the easiest way to conserve battery, do you have them?
Trading generators might still be part of the plan. I am just suggesting to look at all areas to improve your experience.
