This 55" x 21" x 4-3/4" tank is typically used to hold grey water. If you have a 1969 or newer Airstream, you can install a modern 21 gallon tank (or even 2 tanks for 42 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.
55" x 21" x 4-3/4" (allow 1/4" variability)
21 gallon capacity
Food grade (NSF 51) polyethylene (LLDPE)
