My swag, if it has a 300HP motor, an 8 sp trans, you are willing to let the motor rev to where it is making the HP to move the setup. you will be good to around 6000 lbs of trailer. 12-13K total lbs would be my max for your rig.
Looks like your swag is right on since the GCWR of the 3.6/3.55 with the 8 speed is 12,900. That's right about the same towing specs the small block V8s of 20 years ago had. The V6 would probably offer similar performance to a mid-90s 5.9 Magnum V8, although with very different characteristics, like revving MUCH higher. The super deep gearing of the 8 speed transmission would make up for the relative lack of torque when launching.
Thats about the max I would put behind any typical 15 series. I use a max trailer per chassis at the GRAWR times 2. Max GCWR time 2 of GVWR.....That is how it was down back in the really old days before current engineer ratings. Then one would have to setup the drivetrain based on how you would use the setup. So with that in mind.....I swag'd as good as them "En Ga Neers" in Deetroit.......Are there any left there?
