Jackpot! I found some storage containers at Target - Snapware brand - that fit perfectly in the nooks and crannies of our refrigerator! I bought one 10-piece set, two sizes of containers with a locking pour spout and a couple of larger very flat pieces that slide perfectly under the cooling element. OK - so I've made a huge effort to reduce our use of plastic around our house. Most of our storage is now in glass or stainless. But, glass is heavy (and a little precarious with camping)and stainless is pricey and hard to find. So, we're starting out with plastic. (sigh)
Jay and I had separately spotted some plastic (again) drawer units that would fit under the bunk. We decided we'd limit ourselves to one drawer per person for clothes (the boys would share one for now). This way we wouldn't have bags to juggle and we would limit how much we bring. A smaller drawer unit will hold diapers, wipes, etc. for a few more years as well as hats, our toiletry bags, etc.
I discovered our dog kennel fits under the bunk so keeping Sofie in there at night will help limit the spread of dog "fluff."
I think we're ready for our first little outing - a weekend trip planned with four other families.
