    I have a rather unusual '99 C2500 Suburban that has a 12V Cummins and a built transmission. The engine, transmission, cooling, brakes, etc. are all heavy duty and can easily tow anything I throw at it. So I'm not worried about that. I also have a trailer brake controller added by the P.O.

    My question: are there any issues or concerns with the frame if I go about 50% above the max (stock) towing rating? Chances are I'll stay closer to the 8k - 10k range, but just curious what the limitations are if I were to push it.

    as long as your tongue weight isnt out of control you should be fine until a DOT vehicle pulls you over.

    Is it actually illegal for a non-commercial vehicle to tow more than the manufacturer's rated specs?

    Best to run Timbrens or some type of air bags as I have personal experience with bending of the rear shackel and frame hangers bending when tongue loads go above 1200 lbs which is easy with the loads you r talking about. Basically even if the springs hold the weight ok the shackel and hanger get "overloaded" on one side especially when you turn real tight with a weight distributing hitch.
