When I fill up at home I use a large water carrier to get the water to the van. Then use a submersible 12v pump with a short length of hose to pump the water into the tank. I fitted a 12v plug to the pump and plug into the socket in the rear of van. Although it's a bit heavy to lug the water carrier it does mean I can fill the van in one go and it's easy to keep this "filling kit" clean.
I do the same and I take a 10L jerrycan so I can do the same when travelling. It makes it all very easy.
