Custom Fabrication & Installation




At RBX RockBox Offroad Adventure Trailers, we strive to build quality trailers to fit your specific needs and especially your budget! Our RBX Series trailers are built with durability and performance in mind using 14g steel for the box, channeled 3/16 steel frame rails, 3k rated axles in the lug pattern of your choice. And now offering the same strength and durability in our new Aluminum Series Trailers.

Stainless tanks and accessory boxes along with 12v systems available.

RTTs of your choice can be ordered and mounted to our lids.

We can custom build a particular idea you may have or upgrade a current trailer you drag in needing some TLC… the possibilities are endless… well almost. Consignments and trades are welcome.
