When we tell people we sold everything to travel in an rv, we are speaking of most materialistic possessions. For the sake of this article's clarity, it will help to know we aren't talking about everything but our toothbrushes (though some people do strip down that far!)...
We had a large, beautiful home in NW Montana, right up by the Rockies (which we couldn't afford). It had a living room, dining room, 3 bedrooms, 2 bathrooms, kitchen, laundry and garage. Being very tidy, it wasn't overrun with knickknacks and the like, but there was a LOT inside of that home.
When we began selling, we went wild. We actually made up large garage sale boxes that said "today" and plopped them out by the road whenever we were home, opening our garage to anyone pulling up looking for bargains. We did that for approximately three months.
We also went through every movie, CD, book and sold them on Ebay and Amazon. Anything that wasn't sentimental or potentially useful was sold.
We got Rubbermaid bins for everyone's memories, photos, etc. and neatly labeled them, to place in a small storage unit we rented. We also held onto some furnishings that belonged to my grandparents (not much), which we weren't prepared to part with when all of the other changes were happening. So yes, we still have some "stuff" but at this point in our lives it is too precious to let go of. We may go through the storage unit one day and downsize further, but we feel pretty confident we got rid of every materialistic possession we had that wasn't necessary.
You should also know that our goal was to simplify our lives - we were drowning in the expenses of having cars, a house and all that entails. We pulled out way before "retirement" age with no savings, investments, CD's, etc...just the things in the rv and the storage unit...that was it.
So let's get started - and keep this definition in mind...you get to keep any precious memories/papers/photographs and a few pieces of your grandparent's furniture - at least for the first few years!
