The structure of the trailer features a double-hull fiberglass construction formed from multiple molded shell sections, with insulation sandwiched between inner and outer layers. Instead of wood framing, the build incorporates [carbon-core composite reinforcement](https://www.trendhunter.com/trends/2025-supertramp-flagship-ht) to provide structural strength while avoiding issues like rot or moisture damage. This innovative camping trailer integrates an upgraded electrical system built around a 48-volt platform, with provisions for battery storage and rooftop solar, alongside reconfigured living space designed specifically for [off-grid use](https://www.trendhunter.com/trends/abroad-t4). Exterior features include spare tire mounting, roof equipment and protective wheel arches suited to uneven terrain.
