What the heck is this?

yup, two lock arms. I had to use the tool for the less accessible locations. I can't get my arm in enough to engage the rear on any of the driver's side slides.

Additionally I think someone tried to open the front driver's slide while the rear bar was engaged. Seems a bit misshapen. I was able to get it to engage though.

The rear kitchen latch is too easy to engage, might need to ask Newmar if there's a way to make it tighter.
