This is probably a pretty stupid question, most of mine are. Since I need to remove the fiberglass gas tanks and replace them with aluminum tanks I wondered about some changes. I would like to put a queen size berth in the aft cabin of my 34DC. The original has two berths with 100 gallon tanks below each. If I put a single 200 gallon tank centered on the keel will their be any negative reprocussions? I'm not sure if the tanks on each side add to the stability or if it was just designed to give my wife a reason to sleep in a seperate bed.
