I am waiting for 28G bumper pull toyhauler to arrive (ETA mid-march) and researching backup camera options that would work with 2021 GMC Sierra 3500HD.

Has anyone wired the GMC trailer camera to GD toyhauler? Since the 'invisible trailer' would not work, did you chose the existing mount for Furrion camera or middle of the back door? Any tips in running the wire?

I would like to keep the dash clean as GMC has camera wiring, but my concern is wiring on toyhauler on the back door.

28G is 34' long - according to GMC maximum length for 'invisible trailer' is 32', therefore I could not use it for that function, however I could still use for backing up the trailer.

Suggestions appreciated.
