In my experience, those who want to build their own aren't generally interested in pre-built trailers from manufacturers, and those who want to research a pre-built trailer don't usually want to wade through all of the threads about building one in the garage. Those who do want to see all of the threads are more than welcome to browse both sub-forums. Maybe keep the "Overland Trailers" as a main forum for topics which concern all trailers, such as trail techniques, finding a good camp site, recovery, towing advice, etc., then have the other two sub-forums for topics that are more specific to the build process or user experiences/purchase process.
