Wanting to put on a rear step...and not much discussion on it here.

I se for about the same price ($170 to the door) you can go OEM or Aqua Step. I am leaning towards Aqua Step.

Any pros/cons with each?

I did see a thread that mentioned something about reinforcement kit for a 2004. Is that a problem with Aqua Step too?

This will greatly aid my kids doing in-water transfers while tubing and skiing.
