I wouldnt be surprised if it would be cheaper to trade the truck in lol. This would be a massive undertaking. I have seen a thead on just adding the single chmsl camera and it was a disaster and never got it working. I kind of wish mine had the cameras too but Ive never had them before and managed just fine, plus just something else to break down the road. Now the backup camera is a must have hitching up but they all have that.
