Ok, have a new to us this year, 2012 327RES that has a bad smell on a hot day, or really any day where the sun can beat on the front cap. The smell seems to be coming out of where the TV shelf hole deal is. It is a smell I cannot describe, not a dead animal smell, but is horrid. Once it cools off and is air'd out the smell is gone until the cap gets hot again then boom. Any idea's? I know one of these days when I'm not busy I need to pull the shelf and drawers out just to make sure nothing is in there. Its just odd its only that one side and really only seems to come out of the TV opening......

Having a 318SAB with the same bedroom layout the first thing I would do would be to remove the drawers to verify that nothing is there if it is empty and clean then I would look for water marks on the paneling. If so go on the roof check for any possible way that water could leak into the wall. If it has been leaking for a long time there might be mold and that would cause the odor when the Temp rises.
Does it by any chance smell like rotten eggs?
Or....
Might there be a washer drain in that closet...

I just can't describe the smell, kind of a chemical smell of sorts IMO. I'll check for water intrusion. I've been on the roof a few times, washed it and conditioned it all looked good to me but a closer inspection may be needed. I'll also have to check for the washer dryer hookup. The newer units are set up for a wa/dr right there so it is a possibility. I need to pull out the drawers, your suggestions are helpful. Just asked the wife what kind of smell she thought it was she said not rotten animal or sorts, then asked her if it was gassy, and she said the first time she smelt it she did describe it to me as a gassy chemical smell. Might be on the right track if the trap is dry and its releasing grey gas up in there when hot.

I know its a few years older, but maybe its still outgassing chameical smell from the boards or whatever else they use to construct the trailer?
This is our second season, so still a little newer, but the trailer still has that "new trailer" smell to it. And any clothes we bring and put in the closets and remove after a short trip, also has some of that smell attached as well.

So i took the drawers out and didn't seem to find much, one loose drawer support laying in the bottom. Possibly a little bit of water marks on the bottom of the drawer supports? Or could that just be assembly glue? I would think if it were water it would be more than just at the corners and all the "wall paper" looks OK intact no signs of water. I suppose I should rip out that loose piece of paneling on the side and see if there is anything in that boxed out corner, of the "max turn". I would assume that is just the corner build out. Whatcha all think?

That sure looks like water seepage at the corners of the frame to me.
Maybe pull up the carpet a bit for a sanity check?
Best of luck

At this point I would drill a 1-2in hole in the back boards to see what is in there if nothing then you can cover and seal the holes once the draws are back in nobody is going to see them. Did the smell get stronger when the draws were removed?

At this time there is zero smell. It has gotten cool here low 60's for highs this past week, and an odor eliminator, and there is zero smell now. i threw the drawers back in for now. This looks like it may be a job for next summer when the heat returns and i can chase the smell down. I've never really smelled it from in the drawers area though its as if it comes out of the tv hole only. no sign of wa/dr hookup either. :confused:

If your Cougar has exterior "Docking Lights", remove them to gain access to both bottom corners of the area between the front cap and interior wall. You won't be able to see much but you can tell if the insulation is getting wet. JM2¢, Hank

Could it be a venting issue from the black or grey tanks into the attic space that is migrating forward into the front cap and being recirculated through the open hole you speak of?
My black tank will often times have a chemical smell to it when it is working properly in the heat of the day.

It does, but there in a flat area kind of in the middle above the mirror. Like the photo below shows....

And ill check the tank vents, make sure there sealed good at the roof and to the vent pipes all things are a possibility. Keep up the suggestions its all possible.

I have the 2011 and I have never had a smell like your are taking about. I hope you can find the source. We have the same layout. Not sure if you would have washer hookups.

It's also pretty easy to access the back side of the front cap by removing interior panels in that front closet. I had a 12v charging port in the closet that quit working and I had to get behind it to fix a bad wire crimp.

Ok, I'll ask my next dumb question then. I contemplated ripping out some of the paneling behind the drawers, but seen aluminum structure behind it. It is obvious that Keystone's air staples and brads don't stick in the aluminum very well, as half of the "trim" is hanging and loose behind the drawers and in the closet. I wasn't quite sure how i'd properly reattach it, so I figured id leave well enough alone as the smell didn't stink right now. So now the rest of the story? If i take the paneling off to inspect how would you reattach? I have an air stapler, and brad nailer, but i don't see them holding any better than what was done at the factory?

The panels I removed in the front closet were screwed in place. If I had loose panels or trim and I ABSOLUTLY KNEW what was behind the panels I would use short small head trim screws. You can get them with colored heads to match. The tiny nails/brads/staples the factory uses don't hold very well or very long.

So we have the same year/model.............we too have noticed an odd smell, but it comes mostly from the drawers, and does seem to be most noticeable when sun is beating on the nose cap. We kind of thought it smelled chemical-like. Were concerned it could be propane, but we have checked all connections, etc., and have not found anything. Were going to remove drawers as you did to investigate, but have yet to figure out how to get the drawers out, without busting them. Keep us posted on anything you may find, and we will do the same.

If you pull the drawers out to their full extension, on the inside of each drawer guide, you'll find a plastic insert. In the center of those inserts is a small, thin "lever". Push down on the lever on the right side and push up on the lever on the left side and the drawer guide should release the drawer.

We got the drawers out per your excellent instructions! Thanks!
Now, what we found was the the same as the original posting-panel had come loose in the corner, exposing some insulation. Trying not to disrupt original construction, stuck my hand in as far as I could and from what I can tell only thing in there is the insulation. SO, am wondering if it is the insulation that is causing the odor when the sun is beating on the nose cap.
We have had the unit since it was new, and did not notice it in the beginning. So my theory is that maybe the panel was sealed in the beginning, worked itself apart after a while and the opening is allowing the smell of the insulation to escape into the drawer area.
After we disposed of the brads that had worked their way out, we reattached panel by using about half a dozen #8 small x3/4 self tapping sheet metal screws to secure panel to corner strut. As there is no corner trim, used a small bead of caulking to fill in gap.
Headed to to Tucson, so will let you know if this sealed up the escaping odor!

Let me know how it goes, we're winterized till probably april. Sounds like we have the same thing, Wife and I said chemical smell. Didn't really notice it till about middle summer, drawers cubby is only place we smell it. (tx)

Well, my theory above, regarding the insulation has not panned out! Pretty disappointed we noticed the smell again.
Will keep you posted if we find an answer, and hope you will do the same. At least we have found someone with the same problem, and we are not entirely crazy!

Well, got the rig out and once again when the sun beat on the cap, bam instant smell. I had the drawers out again this spring, fixing the board that was laying behind the drawers(it was amazing keystone missed the stud with 2 screws), and did a little more looking in there for possible smell causes, and i didn't see anything that looked like mold or would have caused a smell. The smell is only in the TV hole. I'm going to call the place where the camper was originally purchased as it has an extended warranty on the unit and see if it is something that would be covered. If not, i think I'm going to take a utility knife and cut the paneling out of the TV hole and see what it is in there. The unit has been inside storage since December and the 2 weekends we used it so far this year it has not rained. I would hope its not a moisture issue.

Just spent the last 4 months in Tucson-our RV spot faced north-no odor. Got home, where our fifth wheel faces east, and gets a pretty good piece of the rising sun. Bam! We have the odor back.
Please keep us posted on what you find.

Called original selling dealer and extended warranty seller, and "smells" not covered. We like the unit other than this damn smell, so I took the plunge and tore into it. Slit the caulk pulled the trim and pulled back the upper corner of paneling. NO MOLD in the insulation no sign of water penetration thankfully. Then the old what the hell is the smell. Keep digging around and feel rubber, pull on it trying to figure out what it is and finally dawns on me that's rubber roofing EPDM. When they built the unit my unit and probably yours got the end of the EPDM roll and it did not get cut off and it got left in the cap about 2 feet down on our unit. Further more it is in between the cap, and the insulation. It gets hot and gives of the wonderful smell. I know this because i cut a chunk off and threw it in the microwave got it hot and bingo that's the smell. So now the repair is going to be a little more extensive. My guess is the excess EPDM is across the entire cap. So now the closet doors need to come of and all that panneling needs to be pulled down, the insulation slit, EPDM cut off, and re assembled. So now the next question, how do the closet doors come of? Thanks again for the helps!(tx)(tx)

Well tonight i tore into it, and got it out threw 24" of chloroplast type insulation up on top and wedged it in with a fiberglass bat so it didn't move to reflect off what little i left cutting off with the scissors. Here's what was cut off, and the front tore apart.

What type of material did you pull down, is that a fiberboard or a flexible panel to get to that area in the closet.
And how did you manage to pull it down?
Thanks

It is a somewhat flexible wood paneling that many would call luan I believe. After removing the doors, and the Decorative "header" the paneling edge was exposed between the ceiling and the cap wall. I cut it with a sharp utility knife at both ends that were caulked, and then on the closet side of the "divider" wall, so i could get my hands up in there. On our unit it is pinned on with 18 or 22 Gauge brads that really don't hold well. I started with a straight screwdriver at one end and pry'ed a corner and pulled the rest with my fingers. It wasn't too bad of a job. When i reassembled it I used 1/2" pan head sheet metal screws at the top so it would be easier if I ever had to get back in there, you'd never see them, and pinned the trim.
Who would have thought it would be excess EPDM material? Glad you were able to figure it out and deal with it.
