the tracks are riveted on and they make a lot of noise about weight limits as well as the way loads are secured., going to the point of strongly recommending that canoes and Kayaks be tied down on the front and rear as well. I had the rhino platform fitted to my Navara in 2013 and no mention was ever made, I did heaps of trips, thousands of Klm's and a lot of offroading loaded up as below and never had an issue.How are they fastened to the roof? Rhino rack used to use 5 X 4mm rivets... Number of online profiles where they pulled out the skin with any sort of load attached.
what i am using them for i think they will do the job.
