There I was, … dark and snowy night.

A guy walks into a bar. Bartender says," Awe, why the long face" ( No, he wasn't a horse ). The guy says, " I was in an accident, my car flipped"

Mandolin Dave ( 160 lbs) and some skinny guy to the rescue. The skinny guy and I, flipped the car back over…barehanded. The guy got in… started up, And he drove his JEEP away.

True story

Let us assume we are talking about a tow vehicle's ability to dissipate the difference in potential energy of a truck/trailer combo during the descent of a downhill grade. Let us also assume that the truck is not a hybrid and does not store any energy in a battery or flywheel, and that the speed and associated kinetic energy of the truck/trailer combo (hopefully) does not increase while descending the grade. Then 100% of the potential energy difference (mass of truck/trailer combo times the difference in elevation) must be converted to heat, either through aerodynamic drag, disk and drum brake heating, or engine and transmission braking (or really long skid marks).

Given the above simplified black box model, I find it hard to believe that a light duty passenger vehicle is as capable of converting that energy to heat as a purpose built truck that is designed to do just that. I believe that heavy duty brakes, transmissions, and engines brakes have less to do with total stopping power from 60 - 0 and more to do with sustaining that braking power over prolonged periods of time, as in going down long grades.

Not preaching or advising any course of action, just my thoughts on how I would approach a seemingly difficult problem, using a simplified physical analysis, to inform my selection of an appropriate tow vehicle.

Bigger stuff just means it lasts longer and takes longer to fail under extreme conditions. Bigger brakes will not heat up as fast and wear out soon or fail entirely when the fluid boils and you have NO BRAKES AT ALL.

Yes we can go camping, but sophmorism is essential to the Forum. Many of we lowbrows are unable to rise above it and content to wallow in it. Silliness keeps us going. Anyway, all this physics stuff makes me remember why college physics convinced me to be a liberal arts major. But F = MA means Finance = Mergers & Acquisitions. The symbol F could be replaced by the symbol $. Now you know why I was so bad in physics, though calculus was even worse.



The Airstream is sold; a 2016 Nash 24M replaced it.
