It will work fine just using the battery but as mentioned it depends on battery charge and condition. I prefer to extend/retract either hooked to shore power or running the genset. I find that the slide motors run more evenly and the slide seems to go in and out a lot smoother. I did however upgrade to two house batteries in case of SP or genset problems as an insurance policy. I “test” the slide operation on batteries every 5th or 6th extend. I almost always retract on SP or genset. I like a snug slide while moving.
