Bolted chassis's where mostly for convenience in the old trucks as rivveting was a slow expensive process...
Considering our technology now, bolts are a lot stronger than before...
The other thing to consider is the Chassis rails, they are a lot stronger and lighter too... My old R series Mack had more twists and turns in the chassis than most of the winding roads in the Sth West... But alas, she was built in 1970 and worked the Darwin run, on the dirt for a long time before I got her...
