Yes, same problem. Every Caliber 33 suffers from this affliction. I spoke with Kathy recently, while visiting the Caliber factory, and asked if there had been any reported leakage issues. She says: not with the water tank, but some issues with the
fuel tank. I have some suspicion of trouble with my water tank, but haven't had the time/circumstances to run this down. The only 'fix' I can think of is to cut out the top of the quarterberth, then cut out the top of the tank, fiberglass with
epoxy resin, and re-assemble using dutchmen, etc..
