Try a weekend first. I have a single 12v deep cycle and i go 5 to 6 days before i need to charge. That is running lights when needed and water pump and what ever small amount the fridge takes to keep going.
This is what we do. When we first got our camper, I was talking to a friend (who owns a camper) about buying a generator - he said to wait and see if we actually needed it. It has been 12 seasons of camping, and we haven't needed one yet.
We "dry camp", without electric or water hookup, during the spring and fall. In the middle of summer we camp with electric hookups in case we want the A/C.
