I installed a Fumoto Valve on my 2012 Georgetown and have changed oil at least 5 times and it is effortless to drain.
My DW buys 1 gallon jugs of tea and I away keep two for my oil change.
I have a clear hose I use from the valve to the jug which is placed on the passenger side next to the front tire so I can watch and see when I need to change jugs. It is a bit slow but I'm not in a hurry.
Here is the valve I bought for my F53 engine.

I usually by a 5 qt container and (2) 1 quart bottle to fill mine.
The attachment that others talked about is good and may make less of a mess. I'm almost considering looking under the dog house to see if I can fill from there but I don't think the valve cover has a fill cap like in cars.
