And, if those beads of caulk are on the roof of the trailer of the top of the slides, I am certain that they are not silicone. Anything that touches the rubber roofing membrane needs Dicor caulk, either regular or self-leveling.
I'd also suggest taking a closer look at any other caulk used on the outside of the trailer. In most cases, I think you will find that it is butyl caulk, not silicone. Butyl caulk is the best for bonding to two surfaces and retaining a great deal of flex and some stretch.
