I have the same issue- i purchased the 2019 trailboss earlier this year and only to find out after the fact that GM has not released any info to 5th wheel trailer manufactures on the new frame design and i could not mount a 5th wheel unit sometime in 2020. On top of that my 5th wheel also has the rear camera that will not connect and according to GM factory reps it is because of the software platform they are using and there is no fix. so i paid all the money in the world for whats supposed to be the top of the line CHevrolet product but in return GM has not done their research on the growing RV industry. I am stuck as the dealership is at a loss and the factory reps are no help!
