First off my 21 Ram 2500 (built 11-20) had a guidance line on the cargo camera when I first got the truck (no 360 cams), but I lost that after the first software update and the dealer said it was only for the trucks with the 360 cams… they can’t (or won’t) put it back on…. Well I can deal with that I guess. My problem with the camera is a self made problem… after I put my toolbox on I set a pop can where the gooseneck ball would go (didn’t have the gooseneck ball yet) and I could just make out the top of the can… perfect!!! I could see the 5th wheel hitch just fine. My problem came when I put a Back Rack on the truck and raised the toolbox another 1 1/2”… just bought a new gooseneck trailer and can no longer see the ball in the bed. My question is can I get another camera for the CHMSL and somehow mount it to the toolbox and hook into the radio where the original cargo cam goes??
