Tongue Weight Question

While I take the overall point you are trying to make, and I can appreciate the cautionary sentiment, anything can leave you open to being sued.

Lift your 4unner, add a bumper, change out the headlights, any deviation from stock could be an invitation for a bottom feeder to come suckling.

If you leave your truck stock they could still sue you.

If you take a greasy shit in a truck stop Carlos at Flying J might could sue you for emotional distress.

I don't spend a whole lot of time worrying about the "maybes" in life. If something works fine, it works fine. I'll deal with the "maybe" ramifications later.
