yeah but buckshot even said he only uses it when he needs it and never runs around with it under pressure

my answer to that is........when a weld cracks and he starts trying to build pressure and cant......oh crap it was that huge rock i just tried to climb and only rammed my bumper into.......if he/she is a competent/confident welder then its fine.......i just have never been a fan of the bumper air tanks....i have seen them crack before......they are just not worth it when you have plenty of space elswhere.......like i said i have a 2.5 gallont tank that fits under my hood......jeeps leave alot of room

yeah i suppose i see what u mean

I have welded many schedule 120 pipe joints for a hydraulic system that reaches pressures up to 4000 psi, with two passes of E-7018. One in & one over.

Those joints were holding for more than ten years last time I saw them.

My bumper welds were laid in the same way, & I'm not too worried about them failing.

I am however worried that in the event of a rear end collision, the square tube's seam weld might split if it's pressurized. This is why I drain it before hitting the road.

On the trail, I can't imagine that scuffing it on some rocks would cause that to happen, but I might just drain it for rock crawling as well. It only takes a minute or two to drain it from 130 psi.

I thought about mounting it up underneath the bed, but decided to kill two birds with one stone. I was growing tired of the bumperettes.
