The first 3 trucks I had in my long trucking career, were cabovers. We ran team and did tradeshows and electronics. Last one (12 years ago) was a K-whopper big cab...plenty of room...ran great...but a real pain to sleep in on the move. They do bounce. Add to that, when you shut down in the summer, it takes a while to cool down the sleeper, as the engine is right underneath. Then there is the hassle of lifting the cab for any maintenance, other than fluid levels. It´s a good truck for a single, that doesn´t have to sleep while moving, and doesn´t mind a little extra work, and wants to save some money. They are cheap if you can find a decent one. It was useful getting into tight docks in hotels and convention centers, but most conventionals could do the same, except for the custom jobs. The saying back then was , "if there was an accident, you would be the first one there". Also, they were no fun to bobtail any distance. It´s no wonder they went the way of the Edsel.
