The standout feature of the Opus OP4 is its clever setup. It tows like a compact camper, then opens into a much larger family camping space once set up. The inflatable air tent system removes much of the work involved with traditional camper trailer poles, making it easier to get camp ready and packed down.

For buyers wanting a compact off-road camper with family sleeping capacity, external kitchen, strong touring ability and a practical campsite setup, the 2021 Opus OP4 is a great option.
