[Trailer Trash 2]

I remember when holding tanks were Indestructible they were made from a hard black rubber and were almost 3/16 of an inch thick and I never had one rupture or brake . but with all manufactures trying to get rid of weight they have gone to ABS plastic that stretches' and is flexible when full, the factory put a pressure test on them and they look like a balloon during the test. they are a lot thinner than the early tanks. and a junky construction.
