I’m still working on the Teardrop Trailer Manufacturers page update and searching the internet using Google, I keep coming across websites of shops that build teardrop trailers, including several that are overseas.
Moby1 Custom Teardrop Trailers is another company that offers a rugged trailer for offroad RVing. Their Xtreme Terrain “has a stiffer frame, receiver tongue for multi axis coupler for offroad capabilities, higher ground clearance and rear receiver.”
