Need help in removing the fresh water tank from the V-berth
of my 312 fastech. I noticed theres an aluminum bar holding it
in and I can't seem to get it to move! Does anyone know how to
remove the tank from the V-berth?

Thanks

I believe if you remove the 2 side panels (under the V berth) you can remove that bar. I had 1/2 that V berth apart in my old 312 when I installed A/C in the porta potti "hole".
