You should be able to but it might put a extra load on the charging system. A battery is like the pressure tank on your water system, it gives a little reserve storage. Hope this helps, if it was me I would keep a battery. Jim Oh by the way if you chose not to use a battery make sure you tape the cable ends up so they don't short out.

Your refrigerator, water heater, thermostat, heater, Air Cond. CO and LP detector all work off of 12v. Taking the battery out would make all of those system dependent on the Converter/charger alone. As rvjimmy said, it puts extra work on the converter and leaves you no backup if the converter or shore power goes out. All the above systems would shut down without notice. Not a good idea, especially in the case of the CO and LP detectors. With no power to the LP detector, it shuts of the gas so you can't even light a burner without 12v power in the camper.

Not all LP detectors are linked to a solenoid btw.

I highly recommend you do not run your rig off the converter. The battery acts as a filter and load to the converter and tends to level the output voltage reducing spikes. Spike voltage can blow sensitive electronic circuits such as the refrigerator. The pros will all tell you not to do it.

Depends on the, Some must have a battery, Some not so not so much.

However that said, If you move the trailer without a battery, a fully charged battery (or nearly so) in place, you are in violation of the law in most states as your emergency brakes use that battery as well.
