I'm going to rent a storage building for my Fifth Wheel, it only has a 120v power outlet. If I hook up a trickle charger to the batteries will that be enough for the inverter to power the residential refrigerator. Also, will I be able to operate the slide outs. I can rent another unit that has 30amp service but it's $100 more per month. If I get a unit with no electricity, how will I be able to raise the auto levelers. Thanks in advance for your help.
