If your trailer is longer than 24’ you can’t use the invisible trailering mode. They don’t tell you that.

[@rvgossontheroadagain8052]

our trailer is 31' and we have been using it since we got the truck.

Be nice to know where to purchase the cameras

My prograde trailering is always telling me no trailer connected… trailer breaks work, all the lights work but since the truck says no trailer connected I can’t use any of the “prograde cameras” I don’t feel like a pro

Im having problems with mine blacking out on the screen. Have you found the issue? I've only had mine two months.

Why is there a 100 psi limit on my trailer tire sensors. I need 120 psi for my 17.5 wheels.

[@jellybeansupra]

no you don't

[@davidaustin9927]

Now they need to add more horsepower and torque to beat Ford an dodge an work on the exhaust brake an interior they always add so much stuff but they forget to work on everything

Unfortunately GMC is no longer the same, its quality has become very poor. My grandfather and my father used to buy from General Motors cars, and I also, but modern models have become poor in terms of quality of manufacture, which made me, unfortunately, go other companies. General Motors can not live more than seven years Ksa
