2021 OPUS OFF ROAD 4, The OPUS OP 4 is a revolutionary pop up camper trailer, built for those who want to get out there and experience remote, rugged environments that other trailers wouldn't dare to go. The OPUS OP 4 is lightweight and easy to tow, but built with camping in mind. Developed in Australia for the extreme terrain of the "Outback", the OPUS 4 will go just about anywhere you take it. The OPUS OP 4 does not have a conventional lift system found in most pop up campers, but instead uses a tent supported by inflatable air pillars. The tent inflates in under two minutes! The two reinforced folding lids and universal racking system provides a fantastic solution to store your bikes, kayaks, or other camping toys. If you want to go off-road and off-grid, the OPUS OP 4 is the perfect unit for you!
