dpb,

He's got a 5K tank and wants to trailer 1K at a time. He's intends to
buy the 1K tank. He'll need to clean it before each use of the tank. If
he used it twice in a day I think it would be ok to not clean between
loads. He needs to buy the necessary cleaning gear and be sure that the
tanks are easy to clean .

The point was the dirty "trailer"...the trailer is immaterial; only the
tank.

What's to contaminate it as long as it's closed and used only for
potable water...it'll be just fine.

One other thing that might be worth considering is that El Nino
is brewing in the Pacific at this very moment and it's a big one.
That will almost certainly put an end to the CA drought in the
next few months, so in the range of solutions, he might want
to factor that in. Or maybe secure the tanks so they don't slide
away with the mud....
