One horsepower is the power needed to raise 550 pounds a distance of one foot in one second or the power needed to raise 33,000 pounds a distance of one foot in one minute. It does not care whether the engine is fueled by diesel, gasoline, or lighter fluid. Work accomplished over a specific period of time is what it is all about. It can be an air cooled lawnmower, a Wankel, a turbine, or freight train. It is all about work accomplished with time as a factor. People, including myself, have been fooled by the ratings.
And we create that horsepower in our tow vehicles using torque and rpm. One without the other won't move an inch. The two components together are known as horsepower. Some folks just don't get it. :B
A 737 or MD80 would haul a travel trailer as fast as you'd want to tow it. Might not be much left of it once you get there though!
