Longest Rhino Rack Roof Rack Track Availability and Can Yakima Racks fit Them  

comparing this RRRTS547 to the RT20 track I am looking for as long as possible, strong as possible and Yakima compatibility. Also my van does have a decent lengthwise sloping curve downward as you get toward the front esp approaching the top of the windscreen please confirm/comment to each point when possible, not just answer explicit Qs A Is this the longest track? the RT20 or other RT is not available over 85inch long? B Do both have the Yakima compatibility noted here ??https://www.etrailer.com/question-71634.html and here ?https://www.etrailer.com/question-77423.html ? - C load-bearing strength: 1 seems as though this factor isnt so critical using these naked tracks? of course the van is load-rated lowest, but also sideways/upward forces are relevant also 2 I am planning on using stronger rivnuts to fix to my roof like Ys Plusnuts rather than plain pop pop-rivets 3 as well if possible taking advantage of the existing reinforced mount point holes after I take off the factory rack rails but presumably 4 RT20 would have some advantage there? since RT20 is stainless steel not aluminum, as per http://www.etrailer.com/question-28748.html elsewhere states they ALL are aluminum? D Is it easier or harder to bend downward along the length to accomodate the roof curve without deforming the extrusion profile 1 with a single long track, as opposed to butting two shorter ones up against each other? 2 using stainless steel vs aluminum? Finally E any ideas as to WHY the instructions state the bolts on the ends should miss out on the washers going to the middle ones? sorry for the volume of Qs, thanks in advance!
