Bought a W900 in 97...hauled hazardous materials and plastics out of the Houston area for 12 yrs...did this because I could, not because I had to. All to gather data on tires, their applications, hardware and maintenance issues that exist nowhere else. 4wd vehicles are for the most part oversold and underused. I now own a 2wd F250 v10 with a camper package that was bought for $10,000 under market value because of the demand for 4wd vehicles. If you're a veteran big truck driver you know that 4wd isn't that important unless you do lots of otr driving.
