Boondocking with a RV and filling the water tank with water bottle was a challange.
I found this RV water cap thingiverse.com/thing:2438303 that led me to create a water funnel printables.com/model/334105-rv-water-spout. It worked great however holding a 5 gallon jug with the small tap took too long, Then I discovered this thingiverse.com/thing:4377360 so I modified it to  make the spout longer and make a adapter and fit the 2 together.Â
This worked much better however faster water was still dripping and then I engineered a bigger funnel with a lip to avoid water dripping from the water skin effect.
The adapter needs a little support inside as well as the funnel, however not totally necessary.
