This morning I stopped by the Nissan dealer to try to pick someone's brain about my Titan w/out the big tow. I thought the difference between having the tow package and not having it was the gear ratio, the mirrors, and of course the hitch. When I bought my 2010 i had them throw in the hitch and in with my purchase. I found out I don't have an auxiliary fan nor do I have an extra tranny cooler. The plug for the fan is there and is available from Nissan for under $200.00. I'll go factory on the fan but might go aftrmarket on a cooler Any comments?
