No, it's not even about power. The frontal area constraint is mostly about how hard the drivetrain (engine, transmission, final drive) can be expected to work continuously for sustained periods to overcome air drag and be reliable. If the weak link in the drivetrain chain under sustained load is transmission cooling, then the difference might be made by just a larger cooler... but only the tow vehicle manufacturer knows what they found in testing to be the weak link.

I agree that frontal area is an over-simplification. It's not just the tug variation; it's the shape of the trailer and the relationship between the two bodies. The right spec would be CdA - the product of coefficient of drag and frontal area... but no one will know what that is for their trailer.

Not exactly the dire warnings suggested in this thread.
It's not just performance (how fast can I go, how quickly can I accelerate, how much speed can I maintain up a grade), it's reliability.

That's part of the answer, and if performance was the only issue then a bigger engine might be the entire answer.

Yes, there are lots of factors, and the number of cylinders and whether the engine is inline or a vee are not relevant. Huge truck engines are normally six-cylinders, as is the Cummins turbodiesel in Dodge/Ram trucks that so many people worship. Being in a vee is irrelevant; it isn't a problem (or advantage) for all sorts of commercial vehicle and industrial engines. Engine size is important to how much power can be produced for long periods, but not the cylinder count or configuration.

In practice, most V6 engines in available vehicles are not ideally sized for an Escape 21... but then there are the Ford EcoBoost 3.5L V6 and the VM Motori (sold by Chrysler) 3.0 V6 turbodiesel. Why not just ignore the cylinder count? It would be better to just go by displacement... remembering to count a turbocharger as about a 50% increase in displacement.

Conversely, "V8" doesn't necessarily mean towing ability, even if accompanied by a high horsepower rating. A Ferrari 458 is not a suitable tow vehicle.

But now having heard about "frontal area" do I have to worry about "it" when towing our 17b with our Nissan 6 cylinder ? Maybe I should ask Gbaglo

I haven't had any luck finding it on any of my streaming services in the States -iTunes, Netflix or Amazon - but maybe the Canadian versions have it?

I think Corner Gas - The Movie was on CTV network ( we recorded it to watch later. You could try the CTV site for streaming video.
There is a Corner Gas marathon on Monday on Comedy Channel ( Canada again ).

CTV site says: "Sorry, the video you have selected is not available for viewing outside of Canada." The humor must be to intellectual for us and only appropriate for

frontal area

When I mention the jeep, I guess I should mention the 5.7 engine, 5 speed trans with a good history, the trans cooler and of course the display of trans temp, engine oil temp and exact water temp. all from the factory. After 75,000 miles, half towing, I'll probably buy another. I'm prepared for the I-70 tunnels in Colorado being closed and then I'll just drive over the pass as we used to.
