I've been extremely underwhelmed with the choices (or lack thereof) for running boards and nerf bars for the SR5 and Limited. Our family simply has to have something since it is borderline dangerous for our 6 and 9 year old to get in and out of the back seat without eating pavement (poor design by Toyota in my opinion given they did not include a platform). Apparently it's a difficult design challenge due to the goofy extra wide panel beneath the doors. The one nerf bar I've seen that I like is the n-FAB, and it is currently only available for the Trail Edition. I called nFAB to see if they were planning a version for the SR5/Limited, and to my surprise they informed me they are working on one and that it should be available in "approximately two months." Perhaps the guy was misinformed, but he sure seemed to be in the know. He told me they had come up with a mounting solution and were productizing it now. If any of you out there are also interested in this, I recommend you call n-FAB (1-866-806-NFAB (6322)) and show interest, as I'm guessing the more interest they get, the more likely they are to prioritize it.
