| Owners say | They like how tight the boards sit to the body, the look on half-tons and midsize trucks and the easy bolt-on install, and owners from 175 to 240 lb report little or no flex. The finish is the common complaint: six owners in RB20 and RB20 Slim threads describe the textured powder coat or the bedliner coating flaking, peeling or rusting, from two months to a few years in, and owners in the Northeast and Canada treat the undersides and brackets with Fluid Film, CRC or Line-X before install. | They praise that it works with the tailgate up or down and with a trailer hitched, and four owners report six to 11 years of use, mostly on older trucks. The install draws the complaints: five owners fault AMP's instructions, and on the previous-generation Tundra, five owners sold the wrong part found it hit the bumper or sat crooked until they swapped it. |
| Our verdict | A tight-fitting fixed board with a real step; buy the standard width and treat the finish before the first salted winter. | A long-lived bumper step that works with the tailgate up or down; buy the exact part and budget patience for the instructions. |
