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.
