@Brutal_HO, just as a counter, you see just as many posts where folks ask about towing a 7k tow behind and get "you really should have the stability of a dually" sort of answers. While those may not be negligence in the safety factor, it's surely financial negligence.
The long and short fact of the matter is that you can tow anything so long as your truck meets GVWR and CGVWR numbers. Going over or having too much truck becomes a game of opinions and while I'm sure you believe yours is correct it doesn't mean
@H3LZSN1P3R, myself, or anyone else is incorrect. After all they are opinions.
In my humble opinion, telling someone they need to deal with the additional costs of a larger truck because they are close to, or slightly over, a number many of us consider only used for registration fee collection is, IMHO, not sage advice.
