Sounds like you will have fun. I can talk about water as I think I have figured out a great way to not worry about it.
GuzzleH20 has the idea that you can convert to a setup in your Class A. A little ingenuity goes a long way. I did not buy theirs but created my own.
Think this way:
I want to fill my fresh water tank from “any” water source within 50 feet of the rig. Lake, 1” deep stream, pond, river, creek, etc…
Drop a “sump pump” into the source water to lift it to a bucket by your rig. Now you have to plumb in either a line to the onboard 12v pump or plumb a new pump into your fresh water lines. Then just drop the intake line in the bucket!
Proven concept in my rig!
Standard .5 micron filter
UV light (most expensive item)
