What size tank in 16?

[WhereStream]

New to the Airstream life, with a 2016 16-footer.

We like it and are still learning the how-tos.

Here's one thing maybe someone can help us with. How big is the gray/black combo tank?

The sometimes baffling owner's manual does not say (manual gives gray and black tank sizes for other Sport models but does not provide a number for this model's combo).

Thank you for any assistance.

Saw this on a used 2015 on Colonial's website. Would assume it is the same on your year.


16': 23 Gallon Fresh Water Tank With Drain Valve, Combination 21 Gallon Black & Gray Tank.

Thanks, Piggy Bank, for sharing that info. Very helpful.

Trying to learn how to gauge how much is in the tank and need to know the size to do that.

It has a gauge, but from what I've read on these pages, the gauges are hit and miss, so it might help if I can guess-timate.
