I attached the three sections individually to the cross bars. Two fasteners per section on each end. I covered the open ends of the rack with 1.5" aluminum angle from TSC

May I recommend using a zinc based primer when painting aluminum it will help dramatically when painting aluminum. Worked well for my Jon boat

Painting aluminum is a pain but a few extra steps will really help.
1) Always wear personal protective equipment when dealing with chemicals
2) Clean thoroughly with acetone and let dry.
3) Fill a clean spray bottle with distilled white vinegar and spray down the entire surface to be painted and allow it to dry on the metal. This will etch the surface and promote adhesion.
4) After the vinegar dries completely apply a coat of zinc based self etching primer. Allow it to cure.
5) Paint over the primer with you top coat.
6) Kick back and enjoy a tasty beverage of your choice and admire your job well done.

What tools did you use when completing this build? I'd love to do this myself for my cap but my power tool selection is low so idk if I could do it.
Also I'm not sure what the third picture is in your work shop is. It seems to differ from the rack on the truck, just wondering if I could get some clarification because I'd love to do this myself

Nice roof rack! I would def look into the max wt the stock roof rack can handle if your connecting your rack to it. Usually, it's not much. My 80 stock rack is not rated for much and they are known to fail. Remember, the wt stated is for a load on a smooth highway. Add washouts, whoops or fire roads to the mix and the stock rack might not hold up. I went with Gamiviti rain gutter mounts for my rack. Good luck and cheers!

@Justin Roach,***updated with pictures showing underside***
This rack was built to fit a 2016 4Runner utilizing the factory roof rails.
The short version of how I did mine is;
Using 1"x 2" 16 gauge rectangle tubing, and two pieces of 1" inch angle iron, I made the two cross bars to sit on top of my factory roof rails. The bars are attached to the roof rails by an insert I made to fit into the channel on the inside of the factory rails. Basically a piece of flat stock with two 1/4" bolts welded on. The finishing cap on the ends of the cross bars are some eBay finds.
Next, I purchased a Harbor Freight Tri-Fold ATV ramp. I removed all the hinges and tailgate supports, which left me with three separate pieces. Then using my chop saw, I cut off one section of the three pieces of the ramp to shorten it by about 12-16 inches. Then I clamped all three sections of the ramp together so that the gaps where the hinges used to be, were closed up. This gave me a smooth surface on both sides. Removing all the hinges narrowed the overall width of the ramp by 3/8-1/2 inches.
Then came the task of securing the three sections of the ramp to my home made cross bars. I did this with 1/4-20 nut inserts. For this you would need a tool like this but for threaded nut inserts. http://www.northerntool.com/shop/tools/product_200578285_200578285
Once I had the cross bars centered and evenly spaced, I marked the bottom of the atv ramp for drilling. Using a 3/8" bit I drilled 6 holes, two holes in each section of the ATV ramps where it would lay across the two roof cross bars. Then, using the same pattern I drilled 1/2" holes into the undersides of the cross bars. This was so that I could put in the six 1/4-20 stainless steel socket head screws. I didn't bother capping the holes since they face down.
After all that, I went back and filled all the old rivet holes that I had drilled out with new rivets. Had I paid attention, I could have sorted the three pieces of the ramp so that the outer sides would have needed no rivets.
Then, the last part. I wanted all the cut ends of the atv ramp to be closed up. For this I used 1.5" aluminum angle.They are not water tight, but it looks more finished that way.
Lastly, paint and attachment of the wind deflector and called it a day.....or 5.
*****Disclaimer***** I make no claims to this racks ability to support any weight, Static or Dynamic.
In regards to the pictures, the ones of the rack on the roof of the truck are mine. The picture of the rack on a garage floor was another members rack who posted right below me. I had to look twice myself when you mentioned it.

Hi - what is the exact width of the ATV ramp after you removed the hinges?
And the joints where the 3 sections of the ramp (after hinge removal) look so smooth- they are more than just butted against each other? Did you put something in between to cover the joint?
Thanks!

Looks great. I also did a DIY rack for our Excursion. I was going crazy spending many hrs thinking about what noise she was going to make. On our first run i was amazed at how little noise it made, until i got a cross wind. Well let me say it sucked. So unlike yours, i had to give the wind room to run. So i opened the front wind deflector up and just like that sound gone.Got the wind deflector on today View attachment 23604View attachment 23605

Nice!! I’ve been wanting a low profile roof rack,but didn’t want to pay a arm and leg for one. Going to def try this with some different hardware to make it sit lower.

Here’s how she looks now. Completely detachable for winter but it is mounted to my backrack and full length rails on the edge of the bed

Hey, that looks awesome! What sizes of tubing is that? I’m thinking of welding up something pretty similar.
