Another opinion...
Do not like to be at the maximum of anything of mine
Sure, have pushed it and beyond and that is the main reason for not wanting to push limits...and why love to have 'extra' margin of my own...on top of whatever the designers dialed in
Know and understand the 'half ton' or nothing else will do mentality. Plus know the difference between 'can do it' to 'doing it well & safety'
My Silverado 'can' and did tow a +14,000 lb utility trailer from SF Bayarea to the Tehachapi Mountains to install 350KW wind-generators I designed and installed (had a small alternate energy startup back then). That same TV was loaded to over 7,500 lbs. All guesstimated based on knowing what stuff was loaded onto/into both. The frame was still bent when donated it a few months ago
Bottom line: personal choice and back on the above of deciding on whether you believe in the OEM ratings or not... I like to have lots and lots of margin...to not worry about it. Plus 'ride quality' (that is mostly the reason for folks trying to stick with half tons) isn't on my have to have list...and towards the bottom of my nice to have list...but that is just IMHO...
