Well, so can I...but unlike many, I actually tow/use my truck on a regular basis; use it to renovate my house, get firewood, take trash to the local trash convenience center, etc.
I think we can all agree that anyone actually trying to tow like that would be irresponsible as hell...but as someone who uses his truck on a weekly basis to tow or utilize the bed of his truck to move/dispose of stuff, I don't see that as an advertisement to speed. Rather, I think "Dang...that's one hell of a lot of torque/HP" - and as someone who just towed 5,000# through WV, MO, AR and TN (not to mention VA), believe me when I say that would be useful as hell.
Am I going to go buy one? No...my truck is paid off and does just fine. But would I LIKE to have a truck with that kind of capability? Would it make daily/weekly/monthly tasks a lot easier? Absolutely. (And you're talking to someone who drives VERY responsibly, *especially* when towing.)
