Weight limit on the roof of a 2019 double cab Taco

Can anyone shed more light on what is the max weight limit on the roof of a 2019 double cab Tacoma? I plan on installing a CAB Prinsu roof rack and Ideally like to place my roof top tent on the roof and not ON TRUCK BED?
Thanks

 

Plenty to hold a RTT and a handful of people. Just keep in mind, many of the RTT are very boxy and have a lot of drag. Except to see a drop in MPG

 

Thank you, I plan on installing Orange Virus kit and Pedal Commander as well.

 

If you’re doing the OV tune, pretty sure that takes away any reason to do the pedal commander. I may be wrong, but I’d reach out to OV and get their thoughts before spending money on the PC

 

Thanks for the tip! will do
