The MDT's with the 5.9 or smaler HP motors like this, are ment to ONLY move the truck at gvwr. Many are used ONLY at gvwr, so why put some monster motor in them if they will never hook up to a trailer! My 92 Navistar is that way. Only designed to be a box truck, tow truck with a ramp etc. yeah I do tow with it, but with a 175/335 motor, it does not move very fast no matter how you slice it!
Also, some are only designed to go and operate in a city driving mode. So again, one does not need as much motor/hp as one that goes on the hwy! You will find that larger trucks do not follow the same bogus gcwr rules as pickumups do! THere is no engine axel ratio gcwr for a mdt or hdt truck. They have a chassis gcwr, then a motor, tranny and axel gcwr, based on YOUR specs. If you do local driving in off road situations such as a dump truck, you get a different speced drive train truck than someone pulling/hauling the same load as a person driving up and down an interstate, which gets a different spec as a person using it as a box truck or flatbed.
