I have the factory cargo camera on my RAM and it sure helps for backing in the camper. I have the 2" blue duct tape on the front center of my camper and 2" blue duct tape on my rubber bed mat and it sure helps for lining up the camper as you back in. The top of the back seat is high enough I can't see the floor of the bed. I have the dual alternators also and don't know how much they help for charging but they sure don't hurt and you have a spare if one goes out and the option price for them was reasonable. I really like the nav/entertainment system for phone use and XM radio or Ipod and the navigation is nice to have. I also have the extra factory switches which I haven't used but for the price is a reasonable option to get. I have had my RAM for 10 months now and I am really enjoying it. I also had electric retractable steps installed afterwards and they are one of my favorite adds, they extend down to a comfortable height for getting in and out of the truck.
