Has 3 mounting points and seems plenty sturdy, and it did not come with plastic end capsNice looking Gladiator. I like the wheel and tire setup and I also have a question about your side steps. I noticed on the Rough Country site that these nerf steps only have three main attachment points vs. the four that my stock Rubi rail has. Does the mounting system seem sufficient to keep everything secure? I called Rough Country to confirm whether this style came with the plastic end caps to keep mud and debris out, and they said yes. Can you confirm? Thanks!
