I am an ER travel nurse and used to live in a 35' fifth wheel. We sold that and now live in small, one bedroom apartments as a family of three. We move every three months, and utilize our truck camper between jobs for housing. To keep life simple and clutter free, we literally live on inflatable furniture, and keep our "stuff" to a bare minimum that will fit on a small 4x8 folding trailer that we can tuck away in our apartment or parking space to not pay for storage. I usually work weekends, so every Monday we bail out into the desert or elsewhere in our camper......
Living in a big house full of clutter is highly over-rated, for us right now.
