Water Filtration System
I'm working on a plan for a DIY RV build, and I wanted to incorporate a water filtration system. Specifically, with sustainable boondocking in mind. I'd like to be able to clean any incoming water to ...

You won't (or shouldn't) be able to filter water from any source. There are too many pollutants for an amateur water filtration system.
Recycling gray water may be possible, but if you get it wrong . . .

From the research I've done, there are two solutions that are very similar: reverse osmosis or ultraviolet light. Both incorporate or require a pre-filter.
I use both in my RV's water filtration system. However, I don't boondock.
UV kills viruses and other pathogens, anything with DNA. RO filters out dissolved solids (harmful and non-harmful) like harmful metals.

RO requires higher pressure. UV requires a lot more power.
My RO works fine at 40 psi. My UV system is not a power hog. NSF-certified systems use more power.

My understanding is that RO is the most effective, but least efficient.
The main drawback of RO systems is waste water. An RO filter will "reject" a lot of water. However, I just plumb the RO waste water back into my RV's water tank.
