I installed the RetraxPro FRC-4000 tonneau cover on my '26 black RHO yesterday. Installation was pretty simple. The included instructions are a bit confusing, but RealTruck has a great Youtube video of the install on an F-150.
Clamping the side rails to the bed was easy enough. I had to open them to the absolute max to get them around the inner bed rail. Then tightened them down. I measured at the front and back of the bed and I was off about half an inch. Quick and easy fix with the adjustment allen wrench. Just remember to loosen that clamp first. Getting the right pitch on the side rails was simple with the standoff bolts on each clamp.
Had my daughter help me get the cannister into the bed and drop it in place. It latched into the side rails quick and easy. Luckily my daughter is a lot smaller than me. She was able to get under the cannister and connect the drain tubes.
The cover rolls open and closed effortlessly. I really like the new design as compared to the RetraxPro I had on my '21 Raptor. The handle is nicer, it seems to roll better. The handle would never pop open on my Raptor, I had to pry it up with a key most times. This one pops right open, but it is still brand new. Time will tell.
I love the clean look of the Retrax cover. These last two weeks without a bed cover have really sucked because I have been driving the baby around and I have to keep cramming his huge stroller in the back seat due to rain. Now I can throw that monster in the bed of the truck.
Great product.
@RealTruck was great to deal with. Quick and easy install. Took me about an hour, but I am a bit of a perfectionist. I needed the side rails dead on front and back. 10/10 recommend.
