| Owners say | They praise how low the step drops compared with fixed boards and the Go Rhino E1 (two Tundra owners switched from the E1 for that reason), the short delay before it retracts and the lack of door magnets. Most complaints come at install time. | 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. |
| Our verdict | The power step we would buy for a stock-height truck: the lowest first step in the class, with an install that rewards patience. | A tight-fitting fixed board with a real step; buy the standard width and treat the finish before the first salted winter. |
