I don't think that's "caulk." it looks more like butyl putty to me. But the pictures are so close up that I can't decide if the object is something that would get butyl tape or caulk.
If you decide to caulk, I would recommend the product below rather than use silicone. Silicone is a good seal, but I think of it as a one time use. Nothing sticks to silicone. So next time you have to caulk or touch up, you can't until you scrape and remove and clean off all the old silicone.
I went on a factory tour at Outdoors RV in Oregon. I watched them use this stuff. Cleans up with soapy water, goes on red/brown but dries clear. Easy to scrape off and recaulk as needed.
