Thanks for the Advice
Thank you all for the advice and well wishes. I decided to take our Argosy to the nearest Airstream dealer in the Quad Cities. Overall a pretty clean bill of health. We replaced the inverter, city water hookup, all the faucets and shower, and the toilet inner workings. I also had an Equalizer hitch added. Everything else checked out. We had our maiden voyage to one of our favorite Illinois state parks last weekend. Pics attached below. What a great experience!! The Argosy felt like a second home. The build quality is amazing. I would like to replace the water pump at some point. The original one is so loud it could wake the dead. Another thing we have to get use to is conserving water. The 10 gallon grey tank filled up fast. Again thanks for the advice!
