What Makes This Tank Different?

Unlike standard holding tanks, this model features 60% thicker walls for exceptional durability. The blank tank design means you're not locked into pre-drilled holes that might not align with your RV's plumbing. You can position the outlet, vent, and sensor fittings exactly where you need them.

Installation Considerations

Before ordering, verify your RV's holding tank compartment dimensions. This tank requires a space of at least 70" length x 20" width x 6" height. The blank design requires you to drill and install fittings, so basic tools and RV plumbing knowledge are recommended. Consider purchasing compatible fittings, sensors, and mounting hardware separately.
