I like these ones. I got a kit for my NV2500. I also put one on my travel trailer (camper). I have it on all the time the trucks running as a rearview mirror. The trailer plugs into the same monitor and i can see behind in two mirrors and the monitorI have a camper on my 1999 extra cab.
Looking to install a back-up camera when the camper in installed.
Any suggestions on a good one ??????
