Service bulletins for the 2021 AIRSTREAM Base Camp

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

1STTSB18762820212021-07-19. Service bulletin. EQUIPMENT. It has come to Airstreams attention that the fresh water tank sensor on model year 2021 Basecamp 20' is not reading the correct percentage due to the sensor pad not being cut to the correct size. The tank used on the Basecamp 20 is the same tank used in our Bambi travel trailer. The tank can hold up to 27 gallons, however we are only able to use 23 gallons, therefore if the sensor is installed too low it will still show a percentage of usable water remaining but it cannot be pumped from the tank due to the pick up tube location. By replacing the sensor pad and installing it in the correct location the monitor will show the amount of usable water rather then the tank capacity.
