MHC 331RL - Removing Coroplast seeking tanks

Anyone with a Montana HC331RL that has removed the coroplast underbelly. I'm about to take on the task. I'm wondering the exact locations of the black, grey and fresh water tanks if anyone has accessed them? I want to make sure all 4 are securely in place and what holds them in?

There is an easy way and a hard way to find your tanks. The easy way is come to the rally and tour the factory. The hard way is what you are about to do. First, the coroplast is installed with nails. So, before you start,, go get 100 SS self tapping screws and washers. There are a number of ways to remove the nails. What worked best for me was using a cutoff wheel to put a notch in the nail, the use a nail puller to remove. Not familiar with your model, but all of ours have had the black and gray side by side, with the galley behind that. Our fresh water tank is all the way in the back (just look for the fresh water drain. While you are going through all of that work, do two upgrades. Install SeaLevel Gages and Valterra valves. Hope this helps.

And unless things have changed at the factory, you get to clean out all the construction debris and things dropped by mistake. And you can do some tidy up work on wiring just thrown in. But the knowledge you gain from dropping the bottom/s and seeing how yours was built is pricelss.
