I've watch a video, where a guy used to fill his off-grid generator, by lift 5 gallon jugs (to refill), for a couple years, then he tried one of these battery-powered hand pumps, and mentioned it was a "life-changer". (I don't remember the brand, he had)
Would something like this, work for your situation?
