I don't need to drop a tank. I was just curious after poking around under my trailer today and seeing that the tanks are tight up against the floor. There's no way to access those connections on top of the tank from underneath. They must be plumbed up before they cover the walls just like a house.

From the inside I can see large holes in the floor where the vents and drains come up into the trailer and wanted to seal them up from underneath to keep critters out. But it will be difficult to get access to do that from the inside. I guess since the tanks are tight up against the floor there's probably not much that could slip into the trailer through those holes anyways.
