Polypropylene or Fiberglass BW Tank

Any opinions of superiority between fiberglass and polypropylene black water tanks. I see both are available with the fiberglass tank being more expensive. Mine isn't leaking, but I see stress cracks and since I am replacing the subfloor, now would be the time to replace it.

We've had both in different trailers. They both do the same thing when working right.

We haven't had our polypropolene tanks in our current trailer long enough to have to make any repairs yet. We did successfully make repairs to our fiberglass tank in our last trailer though. However, IMO a fiberglass tank is easier to repair should a small leak occur....but then Mr.InsideOut has lots of experience in his youth 'glassing surfboards.

I went with fiberglass for my 68 because I could get a direct replacement and did not have to re-engineer the dump valve or venting. You will have to attach the flange for the toilet and the vent stack but that is a simple job. The extra cost was worth it to me because of the time saved trying to make a generic tank fit.
