I'm also currently trying to solve this problem. I recently came into possession of a tandem kayak for me and my wife. Already have a RTT on my rack. Thinking of centering the kayak over the rack (laterally) and letting the front half rest on the tent (with padding) and then maybe building a brace that will attach to my roof rack and keep the back half level. Not sure yet, still thanking about it.I know this is old but as I’m just getting into kayaking and a RTT I’m curious too. Are there maybe kits that have raised cross bars so the kayak can sit above the tent.
I’m told the two seater kayak is too big to mount on its side. It’s a tarpon 135t (18’)
