Thule Towers and crossbars 65" long are wide enough to transport (2) Revolutions side by side.
1" pipe insulation held on with velcro strap ties saves you a bundle on carriers. You can slide yaks up onto the pads upright or upside down. I transport mine upright due to RAM rodholder balls on my gunnels. I place a quilt on roof behind rack and lift bow up onto the roof then slide the kayak up onto the rack quite easily and just as easy to slide off. Bow lines attached to tow hooks under front bumper and rear tie down to trailer hitch at rear bumper
