Interior rear lightbar install question

[Protect1989]

Has anyone installed an interior rear lightbar/traffic advisor in a Tahoe (bonus points if it’s 2025+)

looking to mount one on the hatch and preferably not use any suction cups. Any help would be greatly appreciated!

I’ve installed Whelen’s RST in 21-24 and 25-26 PPVs. It comes with brackets that mount to the hatch. Works well and is easy to install once you done one. I like it because it doesn’t mount to the headliner like some units.

Im looking for a much more simple and cost effective build. Might do a Feniex or STL traffic advisor. Just not sure how to get it to stay in the back window (other than suction cups)
