Great product

I was able to install this at home in about an hour, following the YouTube video on the Real Truck website. That was SUPER helpful. Really pretty straightforward. Getting minimal leaks (and I think that's mostly from the gap in the existing tailgate) and I've used it now in 2/3 open and full-open positions to haul things. Looks great on my 2025 Ranger.

Works great!

Fairly easy install. The videos help a lot. I had a slight issue with the rails leaning down slightly after being tightened. This kept the latches from catching when unrolled. After re-installing several times to see if I'd done something wrong, I just used a pair channel locks and bent the rails ever so slightly where the latches would make contact. Just enough to get it to latch without actually being able to see it. Worked great from there out.

BAKFlip HX4

Overall, this cover is great, however there are some fit and finish issues for my vehicle, 2025 Tacoma (6-foot bed). For the finish, many of the foam cushions on the underside of the cover were not applied properly and were skewed. The top rubber cushions near the cab were not sticking completely to the top (still aren't). The fit is a bit off, and the instructions are off as well. For the fit the rails do not cover the adaptor rails on both sides. I assume this is a tolerance issue with the Toyota bed liner, just not enough size accounted for in the BAKFlip design to cover this tolerance. The gap allows water to enter the bed freely, see photos. The mounting of the rails to the adaptor rails cannot be performed as the instruction show, see photos. The elevation of the Toyota rail system is too low for the clamp bolts to tighten when aligned with the rail centerline, as shown in the instructions. This required the clamp bolt to be tightened with the bolt over the bed rail. When the rail clamps are installed in the alternate position on the rear of the bed, the rear set of cover clips will not click, due to flexing of the cover rails. There is too much rail distance from the last clamp shown in the alternate instructions to the end of the cover and the rail just flexes too much to clip in. To remedy, the clamps needed to be installed further toward the back of the bed than instructions show.
