After market back up sensors

I have a 2012 Tundre Crewmax, basic truck, and I want to add a back up sensor system to it. I am not interested in a camera. Just want sensors to keep me from backing into another vehicle, post, fence, or whatever. For those of you that have added an aftermarket system, could you please give me a good recommendation. Wired or wireless. Have not had this truck but about 2 months and the original owner kept it in pristine condition. Has 54.00 miles on it. And, I have already backed into a tree and bent the rear bumper face plate. Just need to get me another face plate and replace. Really like the Crewmax, but it is long. So, any and all recommendations will be appreciated. Also, any recommendations on an aftermarket face plate for rear bumper will be appreciated. Thank you very much
