We have a 2009 Denali 26FB TT. Bought it new. For the last few years it has had an interior smell almost like propane but not exactly. We have had leak down test, no leaks. The odor is even with the propane tanks off. We clean the thing multiple times yearly top to bottom.
The best we can tell the smell is coming from either the stove or possibly the refrigerator area. Open the oven or refer door no smell. Inspected around and behind both appliances, nothing.
Anyone have any ideas.
