No, dropping the Coroplast is about a 15-20 minute job. If the factory used the power nailer to install the Coroplast, it will take a little longer the first time since you have to spin/pull/pry them out. Best method is to pinch the plastic off the head with pliers and spin them out with a 1/4" socket while positioning a pry bar or claw hammer to apply pressure. Not all of them will spin out requiring a little more work with the pry bar. Once you get all of them out, replace with #14 x 3/4 self drilling screws and fender washers.

The tanks in the drop section (bath gray tank and black tank on my unit) run fore/aft. I think the galley gray tank (just forward of the axles) runs side to side, but can't remember for sure. The fresh water tank runs side-side.

There are three probes and a ground. See photo above.

All this information applies to my unit. I think you have the same but no guarantee.
