Looking to get a rack for my 2016 JKU. I want to carry my canoe. My canoe is 17’ but not very heavy. It’s a Kevlar Ultra Light and only weighs 42 pounds. I was looking at the Rhino Rack SG that fits on the drip rails. My only concern is the manufacturer says they can only be spread 31”. I would like a wider spread and there is enough drip rail that I could go a little wider. Anyone using these bars? I really don’t want a system that mounts to the body. Any other suggestions?
