you find out real quick about the strength of the rollbar when you back into a guardrail in a highway spinout doing 55 mph and do two barell rolls and then two end-over-ends. You crawl out through the roof and think, damn what a ride.Depends on what you're going for with this truck and who will be sitting in the back. Long jump-seats won't work with a stock roll bar. The short seats will - so theoretically having the roll bar and a shorter jump seat offers an added level of protection - though there's a lot of debate as to whether the stock roll-bar is really up to the task in a roll anyway...it's pretty thin metal.
Did replace the rollbar tho.
