The 'Apex 23X' is a 23-foot fiberglass trailer, created by none other than Oliver Travel Trailers, that is designed to extend the company’s existing molded camper designs into more rugged terrain.
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 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. Exterior features include spare tire mounting, roof equipment and protective wheel arches suited to uneven terrain.
