At 12 lb out of the mold, the 49H is one of the lightest ways to add 11 gallons of holding capacity to a coach - light enough that one person can dry-fit it overhead in a bay without a helper. That matters more than it sounds on a retrofit, where you may test-fit a tank half a dozen times before the plumbing lines up.
Eleven gallons sits in a useful in-between spot: more margin than the 10-gallon blanks for a weekend of gray water, without stepping up to the bigger footprints. Ronco molds a second 11-gallon shape, the 76H, an 11-gallon heavy-wall version, and one size down sits the 59H at 10 gallons and 28 x 14.5 x 11 inches. The whole ladder from 7 to 50 gallons is in the RV holding tanks category.
Waste duty only - route gray or black water to this tank, never the fresh system. Budget for about 92 lb when full as you plan your mounting straps. One Source Plastics is an authorized Ronco Plastics dealer.
