Dude, I'm just saying. The whole weight of the vehicle is supported by those. Now I briefly looked at a stock coilover vehicle, and what I saw was two big bolts, one at each end. Inserted horizontally kinda like our stock rear shocks. Correct me if I'm wrong, but doesn't even THAT seem a bit more secure than 3 vertical bolts?

First off man, you are talking to a guy that has a purpose built truck for speed and racing, Obviously, i dont think he would BS you into putting something not safe.
Now since you are asking if his setup is safe that means you didnt look at his picture and know what you are looking at, so i will explain this for you...
First thing you bring up is the bolts, well like he said, you dont know what grade bolts he used so they could be any strength, next thing if you look at the pic you can see he has the lower coil over mount actually mounted on the top of the lower control arm and not underneath it like our shocks mount, so that means the weight of the truck is not on the bolts its between the coil-over and the control arm, so if you look at his picture you will see that his coil overs are held in the same way that a normal coil spring is held in a vehicle (sandwiched between two pieces of metal held together by the ball-joints and spindle) in fact a normal spring is just held in by being a sandwich and his is actually bolted in...
you have to pay attention to details
