Yes, absolutely correct. There is a real knack in installing Rhino legs - you have to strain them out towards you (away from roof) as you tighten the bolts - you need 3 hands!! Have attached some pics of my roof before I modded the racks and after. With the weight you will have up there I think you need 4 cross bars too - get someone to watch the gutters and climb up there - they will flex. Also, I started with my rack as close to the roof as yours and ended up buying cross bars to get extra strength and extra clearance above the roof - helps if you have to clean the roof sometime!! (even Deefers need a clean sometimes). After adding the cross bars, using 4 legs instead of 2 and re-doing the install I never had any issue with rubbing and that was on some serious tracks with a load. Sorry, cant find the pics of the damaged roof - but it wore right through the paint and part way through the metal before I noticed it, and it only took a few thousand Km. Just remembered - i actually ended up modifying the legs with a grinder - took off about 3mm following the edge of the leg plus all of the above
