SOS Concepts Rack with kayaks

I’m waiting on a softopper rack from sos concepts and ideally I’d like to be able to carry two kayaks on the sides with a RTT up top. Anyone have any ideas on how I could attach holders to the sides of the rack? Also looking for ideas on an outboard bike setup that would attach to the rack. Thanks for the help.

 

FWIW here's my bed rack outboard racks (BAMF but similar design to SOS). I'm running a 15mm thru-axle so removing the front wheel on every ride wasn't an option on my mountain bike

Fab shop welded on the outboards tabs and I am running Yakima High Roller racks

 

That’s a pretty sweet setup you’ve got there, I don’t think weld on will work for me though as I’m hoping to be able to swap out kayaks and bikes. I was thinking some kind of u-bolt design

 

RTT frames are pretty strong. Any reason you couldn't just lay the kayaks on the tent? Between the bikes.
