Can we do it?

After long consideration of many moving options, we have come to the conclusion it will be best to use ABF U-pack. We are pretty sure we are going to go with the Relo-cube option. Now the question begs, can we fit all we own into one 6X7X8 cube? Currently the answer is no. But we plan on only taking beds, our kitchen table and chairs, only our nicest dishes, and clothes/toys. We already have a huge list of things we are selling at the community sale our complex is having next week, and other things (which include our TV - goodbye & good riddance) on craigslist. And now another question: what will 6X7X8 feet of possessions look like in our new place? (Which I hope will be at least twice as big as our under 600 square foot apartment that we currently reside in...) Looks like we'll be doing some shopping when we get to MD!
