Replacing a failed gray tank in a coach nobody makes parts for anymore is mostly a matching problem, and that is what a four-deep bench of 40-gallon shapes is for.
Full weight is roughly 334 lb of waste. If the 71H outline misses your bay, run the other three 40s - the 5H at 56.5 x 19 x 12.5 inches, the 103H, and the 84H - or step to the 42-gallon 21H. Everything waste-side is indexed at RV holding tanks. Gray and black water only, never potable.
