Alpha 63 Gallon RV Fresh Water Tank - 988BLANK

Upgrade your RV's fresh water storage with the Alpha 988BLANK, a premium 63-gallon fresh water tank engineered to meet or exceed OEM standards. This rotational molded tank features FDA-approved polyethylene construction, seamless one-piece design, and superior durability that outlasts factory-installed tanks. With dimensions of 58" x 39" x 7", this low-profile tank maximizes water capacity while fitting in tight vertical spaces.

Why Choose the Alpha 988BLANK Fresh Water Tank?

FDA-Approved Polyethylene for Safe Drinking Water

Your family's health matters. The 988BLANK is crafted from high-quality, FDA-approved polyethylene that's specifically certified for safe drinking water storage. Unlike some factory tanks that use questionable materials, this Alpha tank ensures your water stays clean, fresh, and safe to drink mile after mile.

Seamless One-Piece Rotational Molded Construction

Engineered without seams, joints, or weak points, this rotational molded tank delivers superior strength and leak-proof reliability. The seamless construction eliminates the failure points common in welded or multi-piece tanks, giving you peace of mind that your water stays where it belongs.

Stain, Corrosion, and Rust Resistant

Built to last for years of hard use, the 988BLANK resists stains, corrosion, and rust even in harsh conditions. The durable polyethylene material stays clean and functional season after season, ensuring your water stays fresh and your tank stays dependable.

Large Capacity in a Low-Profile Design

With 63 gallons of capacity in just 7 inches of height, this tank is perfect for installations where vertical clearance is limited but you need maximum water storage. The 58" x 39" footprint provides generous capacity while fitting into spaces where taller tanks won't work.

Superior to Factory-Installed Tanks

Many RV manufacturers cut corners with thin-walled, inferior tanks. The Alpha 988BLANK is built tougher than typical OEM tanks, offering enhanced durability and longevity that makes it the smart choice for replacements or upgrades.
