Actually, only need one for the back of pickup bed. Have cover over the bed now, would like to work it in with that.

Aluminum rack

I haven't tried one but the reviews are positive. It would set a canoe about a foot over the roof of my cab, maybe top heavy and an issue in strong wind?

Agree. This adjustable model would be better

If your truck has a receiver hitch, Spring Creek Outfitters makes these canoe/equipment supports.

Truck receiver canoe support

Expensive but nice

This is what I bought for my 2 kayaks. They are made in North Dakota and are really great. They bolt on very fast and easy. Plenty of room for your tonneau cover to open and close. These are not one size fits none. You order the correct size for your vehicle. You would only need one rack for your truck so pricing is wrong but you can do the shopping. Adarac truck racks

Thanks
I wanted to go that route but was worried about the tonneau cover to open and close. ordered the other one I mentioned by Yakima that inserts into the trailer tongue. I have from before, another Yakima rack that fastens to the top of my cab.

Holy Cow! For that price I should bust out the welder and start making a bunch.

I have some on my truck right now. Bought them at harbor freight. I believe they were haul master brand. You can usually pick them up for around 200 dollars during one of the sales they have. I have had good luck with them.

Canoe rack hitch extender

This is a lot cheaper than some posted. It works fine. It does wobble so I put a shim against the part that inserts into the receiver. I taped pool noodle parts over the uprights. I can use it down to haul canoe in truck bed, which is super easy for me as far as loading / unloading. When I got it it ran about $87.
