Black tank

[MDTdriver]

Two weeks before my pin box problem, I found my black tank slipping past the sheet metal angle (iron)? This is also a very bad support for the black tank, it had no support straps under the tank, the fresh water tank holds 1/3 of the amount of liquid but it has two straps under the tank, another bad factory build. It nows has 1/4 thick 1 1/2x 1 1/2 angle iron side supports plus two straps under the tank.
Making a Fleetwood product batter than the factory.
