Ronco Plastics

Forty-three gallons does not appear in anyone's marketing plan - it appears when a mold is cut to fill a specific coach cavity to the brim. The 88H is that kind of tank: the lone 43-gallon shell in...

Two features separate the 8H from the plain boxes in Ronco's 22 gallon class, and both are about installation. The end dump puts the waste valve at the end of the tank, where slide-out dump hardware...

Ronco molds four different 35-gallon holding tanks, and the reason is simple: no two coach floors are framed alike. The 90H is one of those four shapes - same 35-gallon capacity, its own footprint...

When a family of six dry-camps for a long weekend, the holding tank is what ends the trip early. The 91H is the answer at the top of Ronco Plastics' RV waste line: 50 gallons, the largest holding...

A 39 lb molding that will carry roughly 400 lb of waste: that ratio is the whole argument for rotomolded polyethylene, and the 92H is Ronco Plastics' 48-gallon RV holding tank in one of two shapes...

At 27 lb of shipping weight for 35 gallons of capacity, the 93H is the lightest of Ronco's four 35-gallon holding shells - a real consideration when the tank is going into a trailer where every pound...

A black-tank replacement is the classic job for the 94H. Seventeen gallons matches the toilet waste capacity of a wide band of travel trailers from the last few decades, and when the original tank...

At about 22 pounds, the 95H is the lightest blank among Ronco's six 25 gallon holding tanks, which matters most at installation time, when you are the one holding it overhead in a wheel well with one...

A 27 lb shell that carries roughly 367 lb of waste - that is a working ratio of over 13 to 1, and it is what rotational molding does well: a seamless polyethylene body with material distributed where...

The 97H sits near the top of Ronco's holding range: 47 gallons of gray/black capacity, with only the 48 and 50 gallon shells above it. This is extended-boondocking territory - a waste tank sized so...

The 98H is the heavy one. Where its 25 gallon siblings blank out around the mid-twenties of pounds, this molding weighs in near 40, and in rotomolding, extra weight is extra wall. Thicker sections...

Pick the 99H up before you judge it. At roughly 44 pounds, this blank carries about twice the polyethylene of most 22 gallon holding tanks in Ronco's line, which tells you where it came from: an...
