Why Choose the Alpha 987BLANK Holding Tank?
When your RV holding tank fails on the road, it's not just an inconvenience — it's a trip-ending problem. The Alpha 30 gallon RV holding tank is engineered to eliminate that risk. Its seamless rotational molded body means there are no glued seams or welded joints that can crack under pressure or UV exposure.
Unlike aftermarket alternatives, the 987BLANK is an authentic OEM-grade component used by major RV manufacturers. That means guaranteed fitment, proven durability, and peace of mind on every trip. Each unit is individually pressure-tested before it leaves the facility — so you know it's leak-free before it ever touches your rig.
The low-profile 5 1/4" height makes this 30 gallon holding tank an excellent choice for RVs with limited undercarriage clearance, while the 56" x 30" footprint provides maximum capacity without sacrificing installation flexibility.

Frequently Asked Questions
What RV models is the Alpha 987BLANK compatible with?
The 987BLANK is an OEM-grade tank used across a wide range of RV manufacturers. Compatibility is determined by your RV's mounting bay dimensions (56" x 30" footprint, 5 1/4" max height) and drain port location. Always measure your existing tank or bay before ordering.
