Ronco Plastics 6H - 27 Gallon Side Dump RV Holding Tank (No Rails) (38.0" x 27.0" x 9.0")

The side dump is the defining feature of the 6H: the waste valve exits through the side face of the tank instead of the bottom or end, which is how many coaches route their termination plumbing when the dump bay sits beside the tank rather than below it. The molding is broad and shallow, 38 x 27 inches across and just 9 deep, so it also solves height-limited installations that the deeper 27 gallon boxes cannot.

It is a gray and black water tank, no potable duty, weighing about 26 pounds empty and roughly 225 pounds full, 27 gallons at 8.34 pounds per gallon spread over a wide footprint that rewards full-length support. If your valve exits elsewhere, the 47H covers the conventional layout at 43 x 22 x 11.25 inches, and if you need the side-dump pattern in a bigger tank, the 20H runs 34 gallons at 63 x 20.25 x 8.5.
