We found it was not something we wanted too often as we normally stayed where the water supply was aproved and mostly just wanted to change the flavor at times.
That left us to use a standard whole house filter left loose to pull out and add the filter cartridge we wanted for the current problem.
Sediment filters if wanting to be sure there was no particle concerns from rusty pipes or charcoal if we wanted to change the taste.
We simply did not stay where the water was so suspect we would feel the need for three stage filtering!
I carried a couple addapters to go between the standard NPT of the filter housing and the hose and a short hose as built for washers to go from the filter to the RV.
That let me place the filter in the wet bay to be out of sight to guard again those folks.
Lots of different adapters in the irrigation fittings of the big box stores made it small enough to not bother if hauling full time but very easy to adapt to any use we found.
We did want to stay with items that were found easily as there were times when the filters reached a point where we wanted to just drop in most any place for new.
