There are also two layers of 2x4 screwed to the floor at each end of the tank, presumably to keep it from sliding from end to end.
Keep your eyes on that fresh water (colored gray) water tank.
They are very famous for cracking at the lower fittings.
Airstream switched in 67 to a different plastic which is white. Our replacement 30 gallon tank, is made with that same material.
Probably 95 plus percent of the gray colored tanks failed.
