I found this item much better than I expected. Bought it to travel 150 interstate miles with a new canoe when I couldn't find a proper roof rack for my short bed Tacoma truck. Though heavily made, at first I thought it was a bit rickety. But, once I strapped my new 15 ft. canoe down to my rear bumper and the front of the bed, it was solid as a rock. Drove up to 70 mph on the interstate on the way home, watching it with a hawk eye and stopping twice to find it remained firm. I now have confidence in it.
Next test will be in the vertical position with a single roof rack on the cab so that I can use my Tonnuau cover but I expect that I'll have to add additional straps to prevent slop in that position.
If you own a pickup and have a receiver hitch installed, this Extend-a-Truck product is an excellent investment. It attaches or detaches from the truck in less than 30 seconds, and it takes less than a minute to launch or retrieve your boat.
It handles a 12' kayak and/or a 17' canoe with equal ease. Actually, it can handle as many boats as you can stuff into the back of the truck, stacked high or otherwise. If you have ever declined to go out onto the water because of the difficulty of loading your boat onto your truck, this product is for you.
