Hey Sundance, how funny I should stumble on your post just now. We just returned last night from a long road trip to pick up our new-to-us 77 Argosy Minuet, and I was laying in bed this morning thinking "Hey! I wonder why we couldn't move that fresh water tank over to the side storage area, that would make the dinette SOOO much more comfortable! What a great idea!"
Nothing is original. Of course I am sure there are issues with moving it, but having re-done all our Overlander plumbing with Pex already I am sure we could make it work. I was thinking on using the larger side storage area under the gaucho instead as the storage area under the dinette is very small. I wouldn't want to travel with a full tank of water though as all that extra weight would be over on one side. Plus I haven't figured out the water fill access yet...
Anyway, I'll check the other threads that were mentioned but you are welcome to PM me with any brilliant ideas you may come up with, and I'll do the same :-) What model Argosy do you have? I'll be trolling the Argosy sub-forums soon for info, so maybe I'll run into you over there...
