Bed Rack RotoPax

I've been shopping around now for a bed rack for a roof top tent. I'm looking to go more on the low profile side to reduce drag but I'd like to have the options for the roto pax and accessories on the side. Whats the lowest profile bed rack I can do and anyone have recommendations for bed racks? I'm going with the smittybilt gen 1 rtt.

Thanks guys!

 

I have the Mid-height RCI bed rack. The thing is built like a tank, stays within the cab profile, and is loaded with options for mounting tents or additional accessories. I love it. The rack is solid once mounted. I've experienced zero flex and no creaks or groans. Hardware is quality and has stayed secure throughout the 3 months I have had it so far.
