Hello, I just bought a 2009 Nitro, and I love it!!! it has remote start and built in navigation. The only question I am looking for help with is, I want to add crossbars for kayaks. I read some have metal brackets? Mine is all plastic. Would this work? 53" Auto SUV Car Roof Top Cross Bars Luggage Cargo Rack Pair | eBay Thank you for your time.
