The 46H spends its 13 gallons on area instead of depth: a 52 x 30 inch slab standing only 8 inches tall. That two-and-a-half-foot width is unusual in the holding line and it exists for wide, shallow underfloor cavities - the kind you find beneath a garage floor in a toy hauler or across the belly of a wide-body trailer.
Big flat tanks need structure, and this one has it: 32 lb of polyethylene out of the mold, one of the heaviest wall builds at this capacity, so the broad top and bottom panels resist flexing as roughly 108 lb of waste water moves around inside. It is a gray/black water tank exclusively - no potable service.
If wide-and-flat is your constraint, two neighbors bracket this one: the 24H spreads 20 gallons across 40.5 x 30 x 5 inches, thinner still, and the 3H scales the slab format to 35 gallons at 64 x 32 x 8 inches. All the formats - cubes, rails, slabs - are in the RV holding tanks category.
