I just posted a new ad on Airstream Classifieds.
UPDATE (8/22/16): This unit has been sold and is no longer available. For what it's worth (maybe this will help future searchers who find this ad), it sold extremely quickly for $50.
This is the control center from my 1977 Airstream Tradewind. It tells you things such as the tank levels, battery state, and is how you turn on the water pump and kitchen fan. You get everything you see here.
You name the price - I don't know how much to charge as I have not seen anymore of these out there.
You can contact us by filling in the form on the right hand column of the ad listing:
