2) Freight being pulled and moved by a diesel in commercial applications makes no sense in a consumer level argument. Those vehicles can have literally millions of miles and often hundreds of thousands of hours on them (in train and boat applications).
A one ton DRW diesel which is the most popular LTL size truck in commercial service moving general freight makes a excellent towing platform for consumers pulling/carrying anything including just a RV.
IMO when it comes to trucks many folks on a RV forum think in terms of pulling a RV only and forget many of us use our trucks for other purposes including commercial service.
