In the late 1970s we ventured across the country from northern California to western Pennsylvania and back through Washington and Oregon in Steven’s boxy old 1965 Chevy van.   Those were the days, my friends. That trip had a lasting effect and over time we realized we were destined to be full time RVers. In 1995 we sold our house and a Recreational Vehicle became our home. An RV has been our home every since.
