Leak in 2015 RoadTrek 210 Popular

[Welshman-ClassB]

I was wondering if there was a design flaw in my 2015 RoadTrek 210 Popular that I just bought. It rained steady for about 12 hours and in the afternoon my wife and I noticed a fair amount of water soaking the walls. It looks like it came through the air conditioning vent in the rear of the Unit. Is the design flaw the way the ac was installed, or some other issue. Has anyone else experienced this issue? If so, what should I do about it?

The air conditoner works fine so I was thinking of removing the ac grill and caulking every seam, nook and cranny I could get too. If I do that, any suggestions on what type of caulk I should use.

Thanks, Welshman

Don't know if you'd call it a design flaw. You have to park these RV;s either level or the front end just a little higher than the rear. You might want to take a peak thru the rear grill to see if the tray is cluttered with stuff. BTW, there is only a 1 in lip at the front of the AC unit. Good luck.

While you are in there, take a look at the drip pan for the AC unit and particularly the drainline. The drains are kind of famous for plugging up over the years from bugs, and debris. There will be drainline hose that probably goes to the below the floor near the right rear corner. If you pour water into the drip pan is should come out the hose quite soon and before the pan is even half full.

As booster said, check the drain pan. Mine has holes drilled near the rear corners. One hole was partly covered so I drilled it larger. I think I enlarged the other hole and may be drilled another one to make sure it drains.

This is the AC well of my 210 with the Coolcat removed. No drain tubes through the body; just channels to the rear for drainage. With enough forward slope, water could breach the opening into the coach. There are 2 upper ducts in the plenum, one visible here on the left, that pipe air to vents above the bed. If the black sealant fails, a water leak may result.

The pan I referred to is the pan of the AC unit itself. Take a look at the drain holes in that. Water should drain into the white portion shown in our pictures, and then drain out the back. I think what happens is that pan gets full of water and spills forward over into the rectangular hole in the black piece in your pictures. I am going on recollection from many years ago so I may be off-base here.

I added holes to the rear of the drain pan of my new AC when I installed it to promote drainage as you describe.

When we bought our used 170 we had some rain leakage in the back. Turned out it was the well nuts that hold the AC cover on. They are special rubber covered 1 inch long nuts that had deteriorated. Everything has been fine since we replaced those.
