Will be leaving this post as chevy can't figure out the 3.73 gears and degrees system issue. Is a super truck but can't use it and haven't for 4 months... chevy tells me 4 to 6 months... not they are buying it back... worst thing I ever did was try this diesel...
There a currently 20 i know of in ND. All with Max Towing gears... 3.73.. it is a math error in the computer and they can't figure it out. I am beyond sad...
GM has no fix for my DEF issue so now I will be ordering a gas truck.. the 3.0 has alot of potential but I need a truck some time the next year to use as a truck... great car until they get the def calculation fixed.

I had max towing package. I tow 8000 5th wheel in ND just fine. If GM can fix the DEF issue. I also have towed 12,000 in dump trailer with ease. Rating on paper 8900 lbs 5th wheel and 13100 lbs bumper.

Worst purchase of my life..
