Need opinions on most critical TV weight limitation
Not fair to ask someone like me, who follows the ratings and system ratings. As I've
been a designer in that process, project manager running design teams, program
manager running whole product teams and up to a manager/exec in a $17BILLION/year
corporation's Strategy & Planning group. I understand both how the system works
and how the bean counter management exec's think and work
Not automotive directly, but never the less Corporate USA
Bottom line is all about making a profit. Not just from sales, but up to and a
bit past warranty coverage
There is margin in everything with a specification, limits and ratings. How much
is the big secret and we on the outside will never know
Meaning that the whole ratings system has a known MTBF (mean time between failure)
of any and everything.
Too small a MTBF and they left money on the table and we benefit
Too large and they lose profits being burned up in their warranty/service side
Why my original comment was to use that diagram as a dart board target
If me, I'd chose my RGAWR, as I know GM buys the axle assembly from AAM. AAM
rates it at 10,000 lb GAWR. GM rates it at 6,000 lb GAWR. Exact same assembly
from AAM is used for both the 2500 and 3500 dually
Going over will not have the axle assembly fail instantly, just sooner
The issue is that there is more to it than just weight carry rating of the rear
axle assembly.
The brakes are the same dia on both the 2500 and 3500 dually...but the brake
cylinders, shoe width, MC bores, proportioning valving, and must/might be an ETC
So, back to the above quoted title question...chose which one you want to break
due to an over load. Will you be able to continue on that trip? Maybe, but most
likely NOT
