This 50-3/8" x 21-1/8" x 3-7/8" tank is typically used to hold grey water. If you have an Airstream, you can install a modern 16 gallon tank (or even 2 tanks for 32 gallons) without major reconfiguration of your chassis frame. In most cases, these tanks slide right between the rungs on your ladder frame and do not hang below the belly pan! We will spin weld fittings on your tank wherever you like for just $10/ fitting.

• 50-3/8" x 21-1/8" x 3-7/8" (allow 1/4" variability)
