Cargo Bed Camera for 2022 Ram 2500?

[cmworleyjr]

Hey folks, has anyone found an after-market cargo bed camera that can replace the standard "3rd brake light" above the rear window in my 2022 Ram 2500 Big Horn? I plan to install a 5th wheel hitch to pull an RV. I'm waiting on the dealership to give me a price for placing one, but in the past I've typically taken the DIY path when I'm able, to save money. I've checked autoanything, realtruck, etrailer... found a site called Infotainment that sells one but it only works through the 2021 models.
Thanks in advance if you have ideas...
