I've had to use my wife's 62 for some light towing on occasion when my big truck was unavailable or in the shop...usually a miserable experience. Additionally, fuel's getting to be an issue. So, to see what advantage there is to going back stock, I pulled my 31x10.50's and went back to 235x75R15's yesterday. MUCH better towing...80 no problem w/empty 18' tandem car hauler! I had struggled to maintain 70 before...less stress and strain on the truck. I'm hoping for an mpg increase as well...it see's 95 per cent on-road use, looks like sh*t tho!
