Hey JW, what was trying to be said is you NEED the battery when towing and should use it while camping. You need it when towing because the brake circuit will need it if the trailer completely separates from the tow vehicle. Also, the fear that a battery spark igniting your propane would have been an issue for decades since the config has been around forever. But, most definitely, if your trailer is in storage, yank the battery.
