A Duramax is the is the best option for towing a bigger TT but the 6.0 is very capable of pulling your rig but you can expect a lot of downshifting on grades. I have been told if the 6.0 has the optional 4.10 differential gear ratio, it makes for a much better tow vehicle. I don't know what the gear ratio options are for a 2013, but it might be worth checking into.
