bed sides crush?

I'm looking to see if anyone or anyone you know has got their bed rails crushed or dented from have bed bars with gear or RTT on them? I've hear to be careful with the amount of wait but many find any threads or pics. i have 2 @RelentlessFab low pro bars and a MT. Shasta on the bed rails and i don't have any problems. Just wondering

 

I have a Shasta and a pair of Relentless tall bars. Its held up fine for the last couple of years, and I'm not a skinny guy. Also have a tool box that sits on the rails. Everything is fine.

 

good to hear. mines been on the rails for like 8 months now no problem too.
