Exclamation Major fresh water tank leak!

I just sanitized my water system with the bleach/water method recommended here.
I had noticed a very minor fresh water leak the last couple of years, but it seemed to just happen for a little while when the tank was full. I could see an occasional drip at the corner of the "dropped" section of the belly pan where I'm assuming the fresh water tank is.
After sanitizing, now that drip is almost a stream and I've lost the whole 50 gallons of water in two days!
I checked the hose connections that I can reach from inside the kitchen cabinet where they go to the tank, and I don't feel anything there.
Is there a common place for the fresh water tank to leak? Is the tank itself known to develop fatal leaks? Are replacements available? What kind of a pain is that??
I'm getting ready to leave for a 3 week trip to the Southwest this Friday, and now I'm a bit panicked.....yikes!

fatal leak? maybe not, here is how i repaired mine

your trailer may require cutting an access hole in the belly pan (unless you already have one). the trick is where. i belive your trailer has a internal drain valve, so looking in from above may give a clue where to cut a hole. mine came from the factory with a access hole. my leak was due to a cracked fitting and a disintergrated 1 1/2" main drain plug.

once you get at it, the repair may be easy as mine was.

good luck

Hi John....
I just got home a beer!
I don't think my trailer has a drain valve and plug like yours. No mention of it in the service manual, and I sure don't see anything under there that looks like what you've got.
There is a large bolted on "support pan" that sticks down below the thin aluminum belly pan that apparently supports the tank. The leak is running out of a corner of that, so I guess the leak could be anywhere in the tank.
I suppose I'm going to have to pull that to see what's up. I don't really have time before my trip for a tank replacement, so I'm hoping that it's something minor that I can fix with one of those plastic tank repair kits if it's the tank itself.
Otherwise, dry camping is out for this trip and that's kinda sad....
Worst case, does anyone know if new tanks are available?? Andy??
