Hello, I'm soon to be the owner of a 2014 Toyota 4Runner SR5 4x4. I want to add black tube running boards. I really like the look of the N-Fab Nerf-Step Running Boards. However, the N-Fab website says they will only work on a TE. I cannot figure out what would be different between an SR5 vs a TE when it comes to mounting these. Has anyone had any experience with installing these? Is there something I'm missing? Seems like they would bolt to the frame so why would they work on a TE but not an SR5? Maybe someone has found a work around on here. Any advice or input would be greatly appreciated. Thanks.
