Recently when filling the fresh water tank I noticed that it appeared to be much lower then I remembered. I drained it and once empty I tried to lift it to where it was before. I found that the tank had not only dropped but had actually shifted 3-4 inches and appeared to be stoped from moving any further by the tank outlet/fill line and the overflows. I decided to pull the tank and reinforce the compartment floor. I did as others did and installed
pt 2x6 "joists" under between the compartment and the frame. I then installed 1 inch insulation under the tank and installed new overflows with valves. I have not added a strap to keep the tank in place but will do that in the next few weeks. I can not believe that other than a piece of styrofoam and the water lines this tank is not secured.
A few photos of the collapsed bay prior to new supports and the tank out of the bay. I did measure the tank it it does come in at 70gallons. It was fairly deformed and is now square again with the Better supports under it.
