Hi and Welcome - I'm not familiar with any control panel in our 78 Minuet other than the fuse controls in upper back storage area. Almost all info we have gotten on "Mini" either came from these posts/threads or out of the Argosy owner manual we ordered. I think what info you are looking for could be in the manual as it provides pictures of elec. outlet locations, capacities of different tanks(clear,grey,black) weight capacities, etc.
We are definitely going to have to look into an Argosy rally here in the near/somewhat near future since so many are coming on board and in close proximity or living in the wonderful state of Colorado!@! Leigh
