And this is where it all goes hay wire. We don't want to accept the ratings.
We want to challenge them and re-rate the ratings.
We want to decide which are valid and which are not.
Which ratings apply to our scenario and which can be ignored.
At some point it boils down to either you abide by them or you don't.
I undersrtand some are tax,ratings and registration ratings but in the end they all serve a purpose.
I don't believe your combo is going to explode if you exceed a rating.
However I firmly believe a combo that is within all of its ratings will ultimately be safer and out perform a combo that is within some of its ratings.
In the end 1500,2500,3500 SRW,3500 dually, MDT,HDT basically step up in performance ratings and capabilty.
Stick with all the parameters and your combo will be fine. Or you can Pick and choose the ones you like and pretend there is no ratings system.
