Consider applying Eternabond to the seams and along the roof edges in addition to inspecting/caulking on a regular basis.
This is exactly what I have done to my last two RV's and will be doing to our brand new 2017 Miramar.
At the very least I would recommend using ETERNABOND "tape" along the front and end cap/roof seal/connections.
I removed as much "self leveling caulk sealant" from those areas. cleaned and prepped it as per the ETERNABOND instructions (very easy to do) and applied the 4" tape across the width of the roof. I then do the skylight, vents, and any other "through roof fittings" that make sense. Once I put that down...I probably don't need to do anything other than inspect it for the next 8-10 years.
I am also considering a full on "sprayed roof"... its expensive BUT, there is nothing (short of a fire, etc) that will ruin an RV like a water leak through the roof.
I just wish OEMs would SERIOUSLY invest in better tech for their roofs... When you really look at how they are made its "old tech" IMO
