ATF: MPG - Storage in MPG185

Just purchased our new trailer and are delighted so far. As a kitchen and space designer, I like to make every inch of storage space count. I would like to know what is behind the eating/sleeping area at the back of the MPG 185. I know the bottom part has the pass-thru area, but am wondering if I could open up the upper part to store bedding etc. Thank-you for your attention

I have been wondering that myself.....easy to make a quick access panel if there is enough room for storage....
