There are welders and there are "Welders" not all are created equal a poor one can destroy a frame in just a few seconds if he's a hack for sure.
So far I do not have frame stiffeners on mine (but do need to get them done) a weak point for sure. What you need to do is take how much money you have in one hand and then what you need/want in the other and go from there. The money hand will empty out much more quickly than the want/need hand by at least 25-1. Don't ask how I know.

Looks like that frame was already rusted/cracked.
It's worth pointing out that a well designed unit body can be stronger than a body on frame, and lighter. I mean look at koh ultra 4 cars, most race cars. They are unibodies, albeit ones made of chromoly tubing. But in this design the body is structural and can make it more rigid while using lighter materials. The roof structure is like another crossmember (if you've ever looked under the headliner). Obviously not as heavy as the "frame" structure, but it doesn't need to be.

Absolutely, when the GM "G-platform" (used in 95+ Pontiac Bonneville, Buick LeSabre/Park Avenue/Rivera/Lucerne, Cadillac DeVille/DTS, etc.) came out they had to use the equipment normally used for heavy duty trucks for the failure testing because the machines they usually used for cars and light duty trucks couldn't break it.
Im not trolling man I promise. I just worry more than others. Im sorry if my first two post made you feel that way. Ill try to be low key. I have better things to do than make a nuisance of my self. But serious who trolls a jeep forum out of all things??? Not this guy.

There are literally hundreds of videos on YouTube of people beating the snot out of Cherokees. A 20 second google search would have shown you that they are tough enough to handle off road abuse, this would have prevented you from being worried sick about something so silly.
The XJ made the Kiplinger list of "10 vehicles that refuse to die". That's how tough they are!
