By "kind" I am guessing you want to know what kind of caulk to use, right?

Almost all of the RV's currently being produced have a "rubber" roof which is actually a material called EPDM. There are some other similar products out there, so it's worth checking your build sheet to verify what actual roofing material was used on your unit. If it is not Dicor or EPDM, there should be some product information in the pack of material that came with the trailer. That would include maintenance information and product recommendations.

If your roof is EPDM, then the usual Dicor caulks are appropriate. Self-leveling for the horizontal surfaces and regular for the vertical seams. There are dozens of previous threads on this that are well worth the reading.
