How do you accumulate so much stuff?

We're trying to get rid of a lifetime's worth of accumulations in just under a month so we can live in a motorhome for a few years. Daily trips to storage, recycle, the dump, Goodwill, Craigslist, give it away, please take it! We have 10 days to closing and the clock keeps ticking. We're both anxious to have this ordeal end so we can return to Arizona and pick up our motorhome and figure where to head. About to be homeless in Seattle! We aren't going to miss this cold weather!
