Select trailer app through your infotainment screen. Create a new profile or select an existing. I believe the next step is selecting conventional, 5th wheel, gooseneck. Transparent only works with conventional. I believe next step is select trailer type. I believe transparent only works with cargo, horse, and one other one. The next step it will ask about transparent setup. This is where you enter your seven dimensions. Next step would be calibrate. I'm doing this from memory so I may have missed a step. #iworkforGM

Flint and Fort Wayne are shutting this weekend due to chip shortage. GM is doing everything to keep the plants running but some of the options maybe limited. #iworkforGM

Plow package is a bigger impact on gas vs diesel. Spring rate goes up two to three steps on gas and only one step on diesel. #iworkforGM

Either go into trailer profile and change one of the dimensions or delete trailer profile and start over. #iworkforGM

There has been some issues with dexter EOH with disc brakes. I believe there maybe a different component you may need to purchase from Dexter. I think the main issue maybe around recognizing if a trailer is attached. There is a thread in towing section at duramaxforum that talks about it. It's probably worth asking some questions between rv and truck dealers. Possibly doing a quick demo. If truck recoginzes a trailer is attached you should be fine but if it doesn't, you don't have brakes. Sorry I can't help more. #iworkforGM

2.5 in rated up to 20,000lbs if properly equipped. #iworkforGM

You should only order the camper package with pickup campers. You need the higher front GAWR for pickup campers and the higher spring rates for roll. On diesels, the torsion bar only goes up one size whereas on gas trucks it's two to three sizes. I wouldn't recommend cognito setup. GM has five different torsion bar rates and there is no way you can replace with one rate like cognito does. It will probably ride nice but, you could have some handling or roll issues due lack of spring rate. #iworkforGM

GMC truck have a whistle that comes from the grill at speeds over 50 mph. There might be a bulletin on it or have your dealer call TAC. #iworkforGM

It will work. You have to use 32' as your max length or it will not accept longer numbers. #iworkforGM

Let me know what model you. Need wheelbase.

Available in work truck trim only. I drove one for about four months on e85. I got around 11 combined mpg vs 13.5 on e10. #iworkforGM

Post pictures of what the trailer camera image is. In addition, it won't calibrate above 30 mph. You need to drive straight under 30 mph. You can turn around or make turns if needed. #iworkforGM

There is a length limit but it will still work if you put the maximum length value in. I believe the length limit is around 10 meters. Convert that to inches and go down an inch at a time until a number works. #iworkforGM

You technically bought a box delete (zw9) package. Do you know if the wiring exists? #iworkforGM

AT4 and Denali have same suspension if equipped the same. #iworkforGM
