Wondering if anyone has seen the Oct 2014 issue of Popular Mechanics, page 48 "Anatomy of a 30,000-Pound Tow Rating"?

It made me think about the discussions (debates? p'ing contests? :-) ) we tend to get in to on these forums when it comes to tow vehicles. Personally, I LOVE the capability of my 2500 Duramax but HATE that it's such a behemoth. Reading this article made me wonder why comprehensive mods to non-traditional tow vehicles couldn't work just perfectly. I don't know how far Can Am's mods go (I think I've seen Andy talk here about hitch mods, frame mods, cooling systems, etc.) but this article/info-graphic covers the Ram 3500 with the 6.7L Cummins (850 lb-ft of torque) and says, "From the lug nuts to the cooling system, a 30,000-pound tow rating requires bumper-to-bumper upgrades."

Some examples:

Driveshaft is 3x heavier than the 1500's with u-joints designed for >5,000 lb-ft of torque.

Cooling fins on the rear differential.

Leaf springs to support >7,000# payload.

A 26" engine cooling fan that moves 10,000 cubic feet of air per minute (compare to the 1500's 19" fan that flows only a quarter of that volume).

14.2" brake rotors (bigger than the 1500's and even the 640hp Viper's) "...important when you're slowing down a load that's about half the weight of a fully loaded 18-wheeler."

Of course, no one needs 30,000# of towing capability (is anyone else hearing Harry Chapin right now??? :-) ) for an Airstream....

Towing with 2014 MB ML63 AMG, Upgrading to 2015 25FB

We currently tow a 16' Bambi, and we're upgrading to a 25FB. How much modification needs to be done to our hitch set-up for the larger Airstream? HELP!!

I can only hope that it receives as many comments as the Lincoln would.

This is fantastic information. I vote it post of the month! I think it is worthy of a thread of all of it's own. Would you please consider reposting this as a new thread? I've been developing a list of things that I know go into the "upsizing" of my truck from a "smaller" base unit. I'm very interested in what components typically get tweaked by the factories vs. the types of components that get tweaked by the aftermarket.
