First TT - Of course plenty of questions!

Disregard? Did you miss the conversation?

I don't see in any "conversation" where you said you've actually weighed your truck with a full tank of gas and done the calculations so you know what numbers you're dealing with. You've also not provided any specifics about your particular truck that would help indicate, regardless of these weight calculations, just how well (or poorly) your truck may deal with towing a heavy load when road & wind conditions are far from ideal. Believe it - a 4.10 axle ratio will be FAR more capable when towing a heavy load than GM's ubiquitous 3.42, or an even worse 3.23. Just referring to an owner's manual or noting the door jamb ratings is a start but to really understand what your truck can safely tow while also transporting your family you really need to go weigh it, as it would sit ready to be hitched to a trailer. Only then will you actually know what the real story is.

I'm done - good luck with your search. :)
