A full 22H is an eighth of a ton of sewage riding your frame: 30 gallons at 8.34 pounds per gallon comes to about 250 pounds, and that number should drive the whole replacement job, from strap inspection to how you block the tank during fitting. The tank itself is a 39 x 25 x 12 inch rectangle weighing about 28 pounds, the deeper and more compact of Ronco's two 30 gallon holding shapes.
Its counterpart, the 39H, holds the same 30 gallons in a longer, shallower 46 x 22 x 9 envelope, so the choice between them is made by your compartment's proportions, not preference. Both are gray and black water tanks with no potable rating, both molded for the daily indignities of sanitation service.
Nearby sizes include the rail-mounted 27H at 29 gallons and the 38H at 32; the full set is at RV holding tanks. One Source Plastics is an authorized Ronco Plastics dealer.
