Water Leak Below Battery Pad

I have a slow water drip coming from the undercarriage under the battery pack and close to the refrigerator vent under the rig. There is no water above the bottom from what I can see but I did notice the propane tank closest to the battery bay door (right behind the battery cluster) is leaning forward as if the legs went through whatever it is sitting on. Any ideas? What water lines are down there?

I stuck my fingers into the gap and I think the metal framing is breaking up because I felt rust chips when I was trying to see if I could feel the source of the leak. Apparently this has been going on for a while because I also noticed a square cutout of the fiberglass that was reattached and caused.

Looks like major bulkhead/basement structure damage.

Those photos are painful to look at.

Great...Im supposed to be driving it up to Michigan in a few weeks. Do I need to worry about the bottom falling out while I am driving down the road?

It will be hard for anyone to advise you on the best course of action without peeling back the bottom fiberglass skin and getting a good look at the metal structure.  Just from your two photos there does appear to be serious compromise of the supporting frame members under the tank.

It seems the be the section right in front of the battery bay. The actual "L" bracket doesn't seem to have a gap.

Looks to be an air tank breaking through the bottom rather than a propane tank.

That rear bulkhead IS compromised.  No idea how badly.

It is the condition of the box beam above the FG floor that is compromised, not the angle.

Kenny,

I'm putting a link below to a thread where a major reconstruction of the coach lower floor structure was performed.  I'm not saying this coach is necessarily the same as yours, or that yours would require this much work.  I just want to give you an idea of what the metal frame construction might look like in the area where you observe the water leaks and "sagging" of the bottom skin.  It appears (from your photos) that there has been some amateur work done on your bulkhead sometime in the past.

I'm sorry this happened. You mentioned driving it. I don't think I would until it's repaired. Best wishes.

I didn't know 1989 GVs had the bottom enclosed. Ours doesn't. But ours is an Oshkosh chassis so maybe that is why.
Looking at the pictures and seeing the condition and combination of what looks like aluminum siding, fiberglass, and lots of caulk makes me wonder if this bottom enclosure was NOT factory.
