black water tank replacement
Just bought a 1974 Prowler, the black water tank is cracked beyond repair, I would like to build a custom stainless steel replacement, will that work or do I need to replace with a plastic one? Thank...

My first TT was a 75 Prowler. My black and grey tanks both sort of disintegrated from age.
They were made of a type of plastic that resembled milk jug plastic.
That stuff doesn't age well. My replacements were the newer ABS plastic ones. I upgraded capacities while I was at it. Those tanks will out last that TT.
I can think of no advantages, and some disadvantages in using stainless.
1. cost
2. weight
3. plumbing it.
#3 might be the biggest headache. All the plumbing I have seen is ABS componenets. Mating that to the stainless could be a challenge
You need to consider the toilet flange. All the ones I have seen glue to the tank. I do not know of a way to do that reliably to a stainless tank. If that comes loose..... Big mess. The vent can be a grommett, though probably not what you will find at the RV store. Those will be for a thicker ABS tank material.
And the dump pipe could maybe be hooked up with some sort of rubber pipe clamp setup, if the size needed can be found.
This could be a trouble spot down the road.
I would just use an ABS tank, and all of the easily obtainable fittings that are normally used.
