2016 35G - In wall structure?

[spydorman]

Does anyone with this coach know if there is a metal structure below the window in back of the drivers seat. There are a couple of tie backs there for securing the table and I need to install a couple more just next to the fireplace.
We have removed the recliner and want to use that space to transport a couple of fold up electric bikes and need to secure them while on a trip.

I looked on the Winnebago site and couldn't seem to find anything shown inside that wall.

Thanks
