I'm not a fan of the rear bumper either! The reverse lights need to be canbus error free or the truck will always think they're out.

The truck gives you fault codes saying your LED lamps are not working even though they do because LED draws much less power/watts than your regular lamps do. The ECU interprets the extremely low watts from the LED as malfunctioning because it is set up to read a certain resistance/wattage from different lamps. You can alleviate this by buying LEDs with can-bus function which essentially tricks your ECU that you have regular lamps instead of LEDs, and your fault codes will disappear.

you need a leveling kit the truck look squat mine was the same so i put a kit.
