Hi JLANDRY I'm looking at a new 15 3500 DRW cc 4x4 with the 410 and 6.7 with the aisisn. I'm having a hard time finding what I want for options. So was thinking of ordering a truck from factory. My question is how do you like towing with the 410. And did u consider the 373 at all. I tow a 15K 5er. Thanks.
