Just ran two loads from the rv, uphill, using the cigarette lighter power cord, into a honey wagon in the bed of a 4x4 (to visualize the incline). Pump did the job well, fast, and was surprisingly quiet.I appreciated not having to buy extra parts just to get it to work. However, I will be getting an SAE extension so I don’t have to park that close.At half the price of the popular one, I’m very happy with this purchase!See full review
