I would believe that with a power up/gravity down system. Our little 16 footer with 2 batteries was only good for 6 -7 dumps until we switched it to power up/gravity down.I have two batteries in both my dumps, I can dump all day long. A few seconds up and down should be no problem even with one battery. If it is, then upgrade to a bigger/better battery. Thats what dump trailers do, they go up and down![]()
