So I am from San Angelo, Texas. And I have a 2022 3500 Reg cab dually Tradesman. And I am going crazy trying to use that little 5" screen to back up to my trailers. I was thinking of just going up to the 8.4" screen, but apparently everyone is telling me I need to do some new 12" screen and I needed to sign up here to get the info on how to do it cheap and correct. So that is why I am here.. Any pointing in that direction would be appreciated.
