Although I do get the good point you are making.

In the example I used, My F150 makes nearly the same HP AND Torque as my 1993 7.3L NON turbo diesel. So, the torque from that specific diesel and the gas 5.4 are nearly the same (within 20FtLb) so it is a comparable "towing accelleration" (from a power standpoint) situation. Again, the point is that POWER (torque or horsepower) is not the issue on an overloaded truck. It matters not if the engine can pull a trailer, it matters if the trailer is too much for the rest of the truck. Much like putting a 2500 HP jet engine in a modified F250. It'll pull a 50,000 lb lead sled at a tractor pull, but put 2000 lbs on the rear axle and first bump you hit, you'll pop both back tires... Ability to pull a load is not an indication of safely towing an RV on the crowded highways when there are other citizens being subjected to the hazardous situation. They have a right to expect those who operate vehicles on the same highway to follow the engineering limits and the laws that govern their vehicle.
