A diesel truck, travel trailer, and quad/SXS add up to a lot. A pilot’s licence and a 170 split 2 ways doesn’t seem crazy now, does it? My truck can burn $40/hr when towing heavy. A jet boat burns $100 bills like dry sticks. Consider your insurance costs on truck, trailer, quad, boat etc. Now consider how a 40-60 yr old airplane doesn’t depreciate.
