The first thing to know about making fiberglass molds is the need for using draft, meaning you need an angle on the sides and typically the roof is not flat either, it will have a slope to it starting at the midline length wise. The second thing to know is you need a radius on all corners. You have to have those two things in order to be able to get the parts to release from a mold.
You should have at least 3 degrees of draft so the parts release form the mold. But on large pieces such as a travel trailer a typical angle of draft is about 7 degrees, and of course it can be more depending on the styling you want.
If you are having trouble finding information for fiberglass mold making related to trailers I suggest you start your learning curve by looking at the marine industry. For instance here is one person's first journey into learning to make molds. SCEADU DESIGN
There will also be technical books available on the subject of making fiberglass plugs and molds. But as before they are more likely to be focused on boat building rather than travel trailers.
I would also strongly suggest you take some road trips to places that are producing fiberglass shells. There likely will be a few within a days drive.
But for a self build I would suggest you consider purchasing composite sheets that have a fiberglass covering. You can build a frame out of aluminum and then you will have a nice lightweight home built trailer. The skills required and the time required for that type of build are substantially less with quite good results.
