Change out all your lights to LED and save a BUNCH of battery power.
I have a Morning Star Prostar 30 and you need to know this; the OUTPUT is limited to 30 amps. I'm sure the input is too, but that's not what is critical. It's the output. Here's why; ever check the current draw on your electric jacks? Mine draw 35 amps if I drive all 4 at once lifting the camper. The Prostar will do it, but only for short durations. I have tripped my controller and even destroyed one, under warranty, if I tried to lift the camper from the ground up to truck-bed height without pausing occasionally to let the heat dissipate.
