It would be very helpful to know what kind of roof you have. Being a new trailer, not many on here will have that model. Is your roof rubber, or metal. That will make all the difference on what you need to do to re caulk seams, usually once per year. For only two months old, I would expect zero problems with the roof. Hang around here though, and you'll find most leaking problems are with slide-outs, an occasional "sky light", and a few trailers with fiberglass end caps.
If you are on a permanent site and want a real solution, build a roof over your camper, and then no maintenance and no worries. You can leave the vents open in the heat, and if you make it wide enough, maybe even a window or two.
