We have a 2014 A122S and it leaked in the front storage area after it sat in some rain. Some water also ran along the inside along the floor of the "mechanical room." (Is there a common term for that area where the water heater/furnace/electrical is situated?)
It was not much water, maybe 4 ounces and I mopped it up right away. It did soak into the rich mahogany particle board
just a little. But functionally, all is good. The boss doesn't like it because now her camper is not perfect any more.
Because the camper was brand-spanking new and there was water on the floor, I worked back through the trail of water to try and figure out the source. Well, I suspect the water was able to enter at the bottom of the seal at the water heater. This seemed really unlikely so I took a hose and ran the water along the bottom. Sure enough, a very small amount of water showed up inside under the water heater. My suspicion was that not enough caulk was used, so I tried to angle the caulk gun to fill that joint and while it worked, I ended up with sticky fingers from trying to get the caulk into the joint. (I may try to invent a disposable U-shaped caulk nozzle for these situations.)
So while pondering this, I rest my hand on the storage door (driver's side front). Well, it sure looked like a good fit but I noticed a small gap. Hmmm? Walk to the other side and inspect. Well, that's something, there is a beautiful bead of caulk on the passenger side front hatch. In fact, all the hatches have beautiful beads of caulk, but not the driver's side storage hatch! You really would not notice it until you got a lot of rain hitting that side of the camper (the storm did come from that direction that day.)
So putting two and two together I think this is what happened: On the assembly line that day the caulk ran out. I am sure someone went to get more caulk but got distracted or something and never caulked that hatch. My guess is they were running low and skimped a little on the furnace seal.
Our dealer would have never noticed. They offered to caulk it for us, but they are an hour away. I got a tube of ProRV(?) caulk and sealed the hatch myself. (More sticky fingers and the bead is nothing like the pros!)
We have been in some pretty good storms since and no problems so far.
That's the only leaking we have seen and I am sure Rockwood would have taken care of it. It was obvious someone missed that hatch but all is good now. We love the camper.
I have some small plumbing leaks, but that's for another post.
