Here's my water transfer setup (except for a short length of hose).
I bought the pump at Menard's maybe 4 years ago. It's now listed at Menards for about $53, but I paid quite a bit less back then. They're all over Amazon for about that price. IMO I think it's worth $53...
I have three of the blue 7 gallon jugs - I always keep an empty one in a storage bay for water transfer if needed. From experience, it takes about 1-1/2 minutes to transfer 7 gallons from the jug to the fresh water tank.
