I 'know' that my toad is back there when pulling the grades or even small hills. You can drive on the straight away pulling just about anything with any size engine but you'll never make it up a steep hill without it floating out with an underrated motor for what you are towing.
I don't know what you are are describing when you say "floating out", but your claim of never making it to the top of a hill is certainly not factual. Back in my youth I hauled coal with a tractor trailer rig powered by a six cylinder International engine that developed about 165 horsepower and climbed some fairly big hills quite successfully. Those loads grossed about 75,000 pounds so what we are talking about here is nothing in comparison. Granted you won't go up hills breaking the speeed limit, but to say you will never make is flat wrong.
