I had a Rhino Pioneer Platform on my Nissan Patrol for 11 years. It withstood corrugations for all those years, over 130,000 kms traveled much of them remote.
It even stayed on the roof of the car when I had the accident, where the combined impact speed was 150-180 kph. I was amazed to see the solar panel mounted on the rack was not cracked or damaged.
The Pioneer Platform had moved about 15cm forward and the six anchor points were still in place, although the one above the driver’s door was only just attached (as the roof was bent by the impact). The car was written off.
The Pioneer Platfrom comes with the INEOS, but it has more anchor points (from memory). I thought the gutter on the IG was not as strong as the Patrol.
