On a non-commercial vehicle, the only thing law enforcement is concerned with is how it LOOKS. If it looks like a road hazard, they will pull you over.
They have this very non-specific charge they can use at their discretion, called "unsafe vehicle." All your vehicle has to do is look unsafe to the officer, and he can hit you with it. Squatting tires, sagging suspension, swerving, swaying, things hanging off... That's what they're looking for.
You can load your S10 with whatever you feel like. If you prop it up so it looks okay and you can drive it straight and keep up with traffic, nobody is going to bother you.
As far as answering your question about what is your weak link, you are not going to find that answer here. You've already done far more research than nearly everyone else here, and know more about your specific truck than nearly everyone else here.
The foremost authority to answer the question at this point is YOU. If you think you can do it, and you're willing to accept any liabilities ranging from breaking something on your truck to killing a busload of nuns and orphans, then do what you think is best.
