About This Van

The November build 2020 Winnebago Mossman B is one of the most sought after caravans in the Australian touring market, known for its rare slide out design, premium composite construction, and exceptional long distance comfort. Built by Apollo under the Winnebago brand, the Mossman B delivers a true residential feel on the road—something few caravans in this size and weight class can match.

The Mossman B is already a scarce model, and there are currently no other 2020 Mossman B caravans for sale anywhere in Australia. Owners tend to hold onto them long term due to their build quality, layout, and the highly desirable slide out bedroom—making this listing a rare opportunity.

At 22 feet, the Mossman B is designed for two to three travellers, featuring a walk around queen bed housed in the offside slide out, a spacious front club lounge/dinette, and a full rear ensuite. The slide out is a major selling point: it dramatically increases interior space, creates a genuine bedroom zone, and is one of the key reasons these vans are so tightly held and hard to find on the second hand market.

This particular 2020 model is further enhanced with a comprehensive off grid electrical upgrade package, including dual lithium batteries, multiple solar panels, BMP Pro charging and monitoring hardware, and a diesel heater—significantly elevating its capability beyond factory specification. And is fully self-contained.

The Winnebago Mossman B is one of the rarest caravans in Australia, with very few ever built and almost none appearing on the market. The 2020 model is especially scarce, combining Winnebago’s high‑quality composite construction and exceptional workmanship with a full slide‑out bedroom and every major off‑grid upgrade — dual lithium batteries, expanded solar array, BMPRO charging system, 3000W inverter, diesel heater, compressor fridge and upgraded grey water. Comparable slide‑out caravans with this level of build quality and off‑grid capability commonly exceed $100,000, making this a standout opportunity for buyers seeking space, durability and true self‑contained independence.
