James Lassoie and Ruth Sherman moved up to a 5-ton 4×4 Sportsmobile (2012 Ford E350 van retrofitted as a self-contained off-road camper) that provides year-round access into remote and difficult landscapes. Needless-to-say, being ecologists, its 10 mpg bred some guilt for them. Hence, they purchased carbon offsets to cover their trips…including a month in Michigan’s Upper Peninsula. Also, they upgraded their 2006 Prius hybrid to a 2020 Prius hybrid-electric that gets >140 mpg!
