Leaks near bottom of tank can be easily and solidly fixed using JB-Weld plastic bonder, some sand paper and fiberglass mesh. While doing that with the coroplast removed, poorly installed Keystone bracing which causes these stress cracks can be fixed by filling space between steel brace in middle of tanks and the tanks themselves with correct thickness of any kind of plywood glued to underside of tank with same bonder. Cracks near tops of tanks are inaccessible for this method, but simply emptying the tanks before getting filled to the top will eliminate leaking and cost nothing. One tip - try to not do too much travel with any of the tanks more than ½ full or even less. Liquids are very heavy and 5th wheels are very bouncy.
