Another what is it?

2021 Jayco Redhawk 24B. While underneath I found some loose bolts going to this. Just queries what is it?

Just from the position and look of it, I would say it is Ford fuel system or vapor system related.

Did you tighten that bolt?

Looks like a skid plate protecting the fuel pump/filter

Engine vapor canister, part of the evaporative emission system. The loose bolt looks like its for the tank shield and needs to be secured.

I would secure any wiring looms while you're down there. I had one break on me giving me a check engine light. Ford fixed it in conjunction with Jayco Motorized under warranty.
