Gardner- I used about half of a box disolved in hot water- makes a brine-
then pour it down the kit and bath drain. My freeze up is the unprotected shower
drain. It does have insulation on it- but right now- its frozen. We poured
some pink stuff down there- looks like not enough. I'm getting ready to hit the
road as when Brenda got home this pm she called me and said it was 74 degrees.
I'm thru with this extreme cold weather camping. Ernie- in 2 degree Montana-
sitting in my warm 83PT40- while the electric meter is having a spasm cause
the temp is going to -14 tonite. I'll let everyone know if we survived.

I am now planning several trips through December in the North East.
Randy and others suggested rock salt in the grey and black tanks to
prevent freezing. When I was planning one trip I thought pink stuff
would do, but now with multiple trips I need a better solution.
Getting rock salt into the black tank is simple, but the grey tank is
another matter. I will need to disolve it in containers of water and
pour it down the drain in the shower or kitchen sink. So how much do
I need to use? I looked up some calculations on the internet, but
they went into molels or some other unGodly scientific terms. All I
want to know is how many pounds of rock salt to protect down to 20
degrees? (60 gallons max)

Gardner, I don't know the correct formula you need but I would dissolve
the salt into the pink stuff if it were me.
