It was hard to believe that the trucks were essentially built on the same frame... his is stiff, but still rides nicely and just feels like a well made vehicle. The work truck was just a 6,000lb torture rack.
Yup. With trucks still being a cab on frame there is a lot to be done with the cab mounts to either make things cheap or dial in ride comfort. Years ago they were just solid pucks of rubber (and still are in the cheap work trucks). The higher trim levels actually get hydraulic mounts similar to an engine mount. They cut out a lot of the vibrations and can isolate some of the cabin pitch that happens when you put stiff springs on the back to support the payload. On the flip side that generally means the fancy trim models have more room for failures and will likely wear out faster.
