Oh please. I do MIL-STD-810G testing across the road courses at Yuma Proving Grounds and Aberdeen that shock and vibe the ever loving crap out of everything far beyond what any person could actually do. Think 8" washboard at 45mph continuously for 1,000 miles type stuff. Lots and lots of assemblies full of bolts pass with flying colors, and welds crack or snap. The reverse happens also, but either way there isn't much of a difference in success rates between the two camps of bolt vs weld. A properly designed system will stand up to shock and vibe. Personally, I prefer bolts to welds since I can easily and cleanly fix a bolt problem, whereas fixing welds tends to be messier. A bolt will only come loose / fail if it wasn't torqued properly into the system, the same way a weld will only go if it wasn't properly applied, or poor design practices.To whoever said screws vs welds doesn’t matter may not have spent much time off-road or on washboard roads.
The vibrations will loosen those screws pretty quickly.
