i have the lok-rak and it kinda sucks. i made 1/8" plates for the backs and it doesnt help, the sheet metal will still bend when wheeling. you wont notice it on the road but when the truck is rockin back and forth on the trail it starts bangin pretty loud and i can see the lip is bent down a little. i used zip-ties and bungees to keep it from being loose and it still bangs around. im plannin on going with a bed bar in the near future. but this is just one mans opinion. dean made a nice rail type jack holder from scratch and its sturdy, doesnt wobble and doesnt bend.
