It is very easy to forget that the space behind those two panels are where the head of the bed rotates down when in the upright position. I recalled this in a reply way back and never had an issue except for our last boondock.
I had evidently thrown my backpack on the bed while under transit. Then a few days later I noticed that it was missing. I event started a family discussion, accusing my bro of 'stealing' the durn thingy.
So when we returned we looked into every Nook and Cranny.....could not find it!
Even looking from the head of the bed....
And wouldnt you know it! Right behind the drivers side access panel!
