Hey guys, apparently the towing capacity for 2009 is going to be increased to 5,200lbs for the 2009 model year. It was mentioned on a GMC Media site I found online. Does anyone know when this will go into actual production? A GMC rep I spoke to when I called said the towing capacity still stands at 4,500 until the new stronger hitch is "validated" and then it will go into the 2009 production. I need the extra capacity, but are we talking days, weeks, months? Why wasn't it ready for the start of 2009 production? If I am not mistaken the Canadian version of the Acadia already shows the increased tow capacity.
