I've shared some related thoughts as a separate thread since this one's a bit old now.

I’ve had Yakima racks on every truck/topper since 1999. This is the first time I ordered the topper with optional Yakima rails. It’s been up there doing the rack thing for three years. No problems, cracks, leaking, etc.
BTW, I only load it like pic to campground about 50 miles across the county.

 

What a great set-up. What kind of Yakima rack is that, and do you know how many inches wide it is? Awesome you're able to load up 2 kayaks + 2 bikes.
