Torque is what moves you, HP is a factor of RPM and torque. You could have an engine that spins 12000 RPM but only makes 75 lbFt of torque (like a motor cycle) and it's not going to pull an RV to the top of the hill even the the HP is a high number.
Look at steam engines, HP in minimal but torque is high and that's what moves things.
The most powerful locomotive ever built turned about 5000 rpm and was not a diesel engine.
The engine that can make the most horsepower will always win period.
Torque has no meaning without the time factor and then it is called horsepower.
If your 12000 rpm motor only made 425 ft lbs of torque it would be waiting at the top of the hill for any of the current diesel pickups and would have no trouble pulling any RV made up any paved road in the USA.
