Load capacity of roof racks
Hi!! I'm curious about the dynamic and static weight capacity of the stock roof racks on my 1999 4Runner. I want to put a rooftop tent on there (weighing 100lbs). Then 2 people sleeping in it = 275lbs.

I was looking at a stock cross bar the other day - it said 165 lbs 'evenly distributed'.
I think that's more the limitation of those crossbars themselves (with their plastic ends/feet) than the rails and roof itself.

Safest is to use custom roof rack with metal mounts.
OR after-market cross-bars and fabricate your own mount using a solid material such that the load will be on metal crossbar and on solid mount.
Example:
Take solid block of delrin or aluminum, drill clearance holes, use t-nuts / t-bolts to mount block on factory rail like this:
Mount after-market cross bar on solid block with something like this...
Next safest solution is aftermarket cross bars with metal towers on the stock rails of the 3rd-gen.
