Another new guy here, getting ready to buy a 2006 slt long bed with a manual 6 speed and 5.9. I was wondering if this truck will have any problems with a gooseneck load of 14,000. 10,000 on the trailer and 4000 trailer weight? This is my first diesel and tow 2 times a month approx 400 miles round trip. load will be hay. Thanks for your input, gshark.
