We used to take those disposable 2gallon jugs, but a few leaked all over while we were away/sleeping.
I installed this water filter and spigot in the kitchen.

Now we drink the water from our tanks. It's really nice not to take jugs, and since we have a smaller trailer, it's really nice to not have jugs taking up counter-space.

We have the same water filtration system in our home and liked it. The RV kit includes a filter bypass bit so you can easily remove the filter and still winterize the drinking water spigot.
