I had a blow out on the road that took out my unberbelly enclosed sealed sewage bay. The enclosure is one entire piece that incorporates the tanks. So replacement was not an option.
Luckily it did not rip the actual tanks just the enclosure part for the dump assembly. Which the blown tire sadly did destroy also.
I used turn buckles to bring together the split parts of the plastic walls. Worked so well as a temp fix I have just left it. Turn buckle fix is still going strong 6 years later.
We must be willing to get rid of the life we've planned,
so as to have the life that is waiting for us.
