## Customer Reviews

### ⭐⭐⭐⭐⭐ Watch out when drilling
*by T***. on December 3, 2024*

Really nice and sturdy and fits the Rivian great.Don’t make the mistake I did - because the bed has a plastic-y liner, I assumed I had to drill another layer deeper to get to metal, so after drilling the outer layer, I drilled into the next layer a couple of inches in. But outer layer of course is metal (under the surface liner) and more than enough to support the screws.I hope I didn’t damage anything?

### ⭐⭐⭐⭐⭐ Easy to install
*by K***N on October 24, 2024*

Directions and templates were spot on. I was a little hesitant to drill a couple holes in my new truck, but the templates were spot on and the extender works ( and looks ) great

### ⭐⭐⭐⭐⭐ Good fit
*by N***M on April 15, 2024*

Purchased for my hisbands r1t. It's a good fit and easy to use. Assembly was not easy but it was still a 1 man job.
