The normal answer is always have a fully charged battery installed. That is because most folks actually MOVE their camper around and the brakes won't work if you breakaway without one.
Additionally, there is a caution about high loads burning out the converter if a battery is not installed, so running the slides in and out without a battery is Verboten.
In YOUR case, a seasonal site that will never be moved and slides that are perpetually out and never retracted, it gets complicated.
Your converter "should" provide all the "normal" 12 VDC you will ever need.
However, if anything ever happened to your converter you would immediately lose your fridge as 12 VDC is required to power the control board that manages the AC heater element that cools the fridge. You would not be able to switch to propane to run the fridge; use the furnace; manage your tanks; depending on model you may not be able to use the microwave; or use any lighting in the camper until you replaced the converter.
