If we keep the OP in mind then what WE drive or how far we have driven it doesn’t matter. He is obviously concerned about safely pulling his trailer and our answers should reflect that. You can argue all day if it is right or wrong but my answer will be:
A-This what you might get away with short term
and
B-This is the best truck to tow with

If you are considering less than B to replace A you should consider SAFETY above conienence in all but the most extreme circumstances!

Suggesting it is no big deal to buy a truck that does not perform it’s most demanding task with a good safety margin is irresponsible.

I suspect most folks would be better served to buy a duall strictly to tow and a small car as a daily driver. In the long term it would end up being less expensive I suspect as you save on fuel and the big expensive truck will last longer.
