Thanks Chris. I am getting the Reconn deck towers installed in a couple of days, along with an iKamper Skycamp mini roof tent. My truck came with the Mopar tonneau cover and I like the idea of keeping the tub content covered and out of sight. I've made contact with a local automotive canvas company that seems to be able to custom make/adapt a cover, but figured that I'd get the RTT installed first and then go and talk to the canvas guys.
Have you given any thought to a cover that has cut-outs for the tower legs?
Just an update: I now realise that Rhino-Rack is an Australian product, which probably explains why it has such a dominant presence in New Zealand. I spent hours looking at all the posts that others had made, to help me with my decisions, so a big shout out to the entire forum membership. I went with the Reconn towers, then the iKamper mini, plus the Sunseeker, and clamps for my fishing gear and shovel. And all to stay within a whisker of the clearance height in my parking garage.
