OEM Gas Tank Skid Plate?

Just noticed that my SR5 V6 did not come with a gas tank skid plate ("shield"). Its just the plastic bladder hanging down.

1. Is this normal?
2. Is this a concern? I drive on dirt roads, but no crawling.
3. Will this OEM shield fit by itself or do I need to buy other things to make it work? https://trdshop.carlocktoyotaoftupe...MIoNj40KHX8gIVsxx9Ch0jCAqmEAQYAiABEgKi3vD_BwE
4. Is the OEM shield metal?

 

No it's plastic and you have to get new gas tank straps that have studs at the bottom . RCI makes a nice metal one and they also sell the straps

 

It's plastic save your money and buy an aftermarket one

 

I have the RCI aluminum on mine. I forget the price difference between the OEM and RCI , but after thought the OEM would be almost as good, possibly fit better.

 

And yes it's normal for it not to have one, they're standard on OR trim, not sure about Limited.
My thought on the plastic shield being on par with anything else stems from the fact that they're hanging off of little studs attached to the tank straps. A true skid IMO should be a shield integrated into the frame and or cross member or both.
