anyone have these tracks of a newer rubicon? i got a 2017 rubicon and haul it on a aluma 548 trailer, the trailer is 54" x 96". i ordered the tracks and was wondering if it will be less than 54" width to fit on my trailer? or do i need to buy a wider trailer? i heard it adds 3.5" width but is that total or 3.5 on each side?
