V or notched doesn't help much. All the strength relies on the strength of the welds. Those brackets need to be better supported and reinforced. I am planning my bumper build and wil be running the brackets all the way through the bumper with welds on the inside face as well as the outside face of the bumper. This will help dissipate all the "pressure" when pulling. Remember; the Jeep weighs 3,000 lbs and takes very little effort to move on flat ground, but when it is stuck or broken, that 'weight' increases exponentially. If i remember correctly as you are recovering a stuck vehicle every 6" of mud it is stuck in adds somehing like 1,500 lbs to the weight of the vehicle. Something like that, not positive on the exact number. My point is, once you are stuck it will take ALOT of pull to move the jeep. You need to plan for all that ahead of time. You saw the previous post where nothing but slow speed steering bent 3/4" plate. Just imagine the forces involved to pull it up a hill. Over engineer it bro! I am designing mine to worst case scenario. I want to ensure that if something horrible happens like the jeep starts to roll over, any single pull point will be capable of fully witholding the entire weight of the jeep and then some. This isn't a tinker toy set you are working with. When something like a tow hook breaks, it can cost someone their life.
