Hey guys, I am looking at getting a RTT for my Subaru Forester 2014. It has raised roof rails. Question is do I need a steel roof rack to fix the RTT? Or would the cross bars be good enough to hold a RTT which weighs about 65kgs? I am looking at buying a Kings RTT. I am an occasional camper , may be 4 times a year and not more than 1 week long trips. Any suggestions ??
