a rear tire carrier bumper is in my plans for my truck, i love the look of them and they are pretty practical, to me at least, they make locks for the tires, actually you can use wheel locks if you want, i had one on my jeep and i used wheel locks and i had a spare tire cover so the tire and wheel wouldnt get all messed up by the elements, it worked great, i had a flat on a trail once and it is by far the easiest way to get to your spare, cause its right there and you arent picking it up off the roof or digging around through all the crap in the back to get it out, i was camping too so i had tents and bags and a whole bunch of stuff in the back of my jeep so it worked great
