I've been a truck enthusiast since I was a little kid back in the 60s. When we traveled to Grandma's house 5 hours away, I'd always admire the trucks on the road with us. At that time there were probably more cabovers than conventional tractors of all brands, Mack, Pete, KW, IH and Freightliner to name a few. Today I only see the occasional Freightliner in cabover trim, with the exception of special purpose vocational trucks. I think most manufacturers have dropped over the road cabovers from their lineup. Why is this?
