We picked up our 560 last April and have been enjoying it since. We went the melamine route for our plates and bowls. We bought random patterns, bought them individually just so they weren't all the same. As far a silverware, just a simple set from Walmart, nothing fancy. The rule for us is no glass containers in the trailer, just to be safe.
We have arranged and rearranged our gallery and now we have it the way that works for us. We use the top left shelf for everyday cooking items - cofffe, spices, condiments, oil, sugar, flour, pancake mix (coffee, flour etc are kept in plastic air tight containers). In the top right shelf, we store 6 plates, 4 bowls, 2 mugs, small camera, and 8 vintage aluminum cups. In the small cabinet under the top right shelf we keep insulated coffee mugs, French press, stove bic lighter, 2 plastic wine glasses, deck of cards, sandwhich bag with sweet & low packets, etc.
Over time you too will find your system and what works best for you. Enjoy and safe travels.
