Dimensioned Print and Gallery Views
The original print shows a 60-inch length, 28-inch upper width and 7-inch maximum envelope. The sloped tank has multiple depths, including a 6 1/8-inch section; that section is not the full envelope. The print identifies a 3-inch offset outlet, 1-inch vent tube, a 9-inch drain region and a 40-degree relief at the opposite end. Check connection and mounting geometry in the original drawing, and allow installation and plumbing clearance.
The rendered gallery and rotatable model are print-based reconstructions, not measured manufacturing CAD. Compound floor interpolation, molded relief details, wall profiles, seam blends and undimensioned vent position/projection follow drawing proportions. Use the retained blueprint for fitment.

- What are the dimensions of the 29 gallon rv holding tank? The original print shows 60 inches long, 28 inches wide and a 7-inch maximum envelope. Its sloped body includes shallower sections, so 6 1/8 inches is not the full installation height. Check the original drawing and allow plumbing and mounting clearance.
- Is the 29 gallon rv holding tank compatible with fittings? The print shows a 3-inch molded outlet and a 1-inch vent tube. Separate valves and adapters are not shown as included. Check their positions in the drawing against your installation.
- What material is the 29 gallon rv holding tank made from? The tank is made from black polyethylene with a wall thickness of 0.180 inches.
- Can this 29 gallon rv holding tank replace tank model number 4339? Compare your existing tank with the retained H1129000 print: 60 x 28 inches with a 7-inch maximum envelope and the illustrated offset outlet. A model-number association alone does not verify identical mounting, clearance or connection layout.
- What is the top connection shown in the print? The print identifies a 1-inch vent tube; it is not described as a sealed, nonfunctional manufacturing hole.
