honest advice on a truck for towing 10000lbs

Unless you live above 8k feet, there is 0 chance you are driving or towing at altitude more than me. Both vehicles I drive have forced induction and I would not change a thing for daily or towing. I notice a big difference when I drive my wife's Sequoia.

I understand your preference for naturally aspirated, but when the altitude changes, it's hard to argue the advantage forced induction provides...given everything else is fairly equal.
