Possible grey water tank leak

I have a 2009 holiday rambler Savoy Lx. I've recently noticed water draining from my underbelly. Is there anyone with tips or tricks for diagnosis of the problem or tips on taking down the underbelly coverings?

The coroplast, corrugated underbelly, is likely held in place with either self tapping screws or a nail type rivet. If screws, get a drill driver with the appropriate socket and remove one side to look into the cavity. If the nails, you may need to use a screwdriver and hammer to loosen then the claw hammer to pry them out. There may also be an insulating foil liner above the coroplast and possibly a tape holding the parts together. If the tanks are more mid ships, then you may find it helpful to cut the coroplast side to side and peel the coroplast either to the front or rear. Probably starting on the street side would be advised as that likely has more potential plumbing.

I would pressurize your water system, and check and tighten every water connection you can find. Keep in mind water can travel a long ways across the Coroplast, so the leak might be far from where itís dripping out. Be sure to check the drains as well.
Should you need to buy Coroplast, sign shops usually carry 4 x 8 sheets of it.
I don't have to have all the money in the world - just enough not to worry about it.
