Where to Mount Roadmaster Invisibrake on 2021 GMC Sierra 1500

Question:

Do you have a photo of the Invisibrake mounted in a 2019-2021 GMC Sierra 1500 or Chevy Silverado 1500 ?? The etrailer info indicates it should be mounted under the back seat. But the under-seat storage looks like it would not allow that location unless the storage bin thing is modified or taken out. Guidance?

We do not yet have any photos of the Roadmaster Invisibrake # RM-8700 mounted in a newer GMC Sierra 1500, but the beauty of this system is that it can be mounted anywhere. On the product page it mentions that the most common installation spot is under the front seat, which is where I recommend installing; you'll only need about 3" since the Invisibrake is only 2-3/4" tall. Under the back seat would be acceptable if you can find a way to fit it in the under seat storage or you can remove it if necessary; I would just find a different spot to mount it.
