Hello, I have a 2010 chevy 1500, 4.8 V8, 3.73 rear axle. the book says i can tow 6700lbs off the tail. but it doesnt say anything about a 5th wheel except that the tongue weight goes up to 1500lbs. so my question is can i tow a 5th wheel? does the towing capacity increase if I can. I have been googling for an answer but I have been getting mixed results. some people say the weight goes up and some say it stays the same. thanks for the help.
