Air-spring trailing-arm suspension maintains the van's set ride height whether you're loaded for a weekend or three months — so you're not running soft on the bump stops late in a trip. Paired with Bosch ABS (anti-lock on the trailer wheels) and Bosch Trailer Sway Control, which dampens snaking via brakes. The coil-equipped Sting can't do any of that.

The airbag system, the 10kW EcoFlow, the composting toilet, the slideout kitchen — none of it matters on a 10-day school holiday loop. All of it matters on a three-month lap of Australia. Sting Air is built for buyers in the second category.

833Ah lithium, 3,600W inverter (5,000VA upgrade available). Runs fridge, climate control, induction cooktop, and charging for five days without shore power. The Sting's 5kW handles two nights well; the Sting Air's 10kW handles a week. The difference is which trip you can do, not which appliance you can run.

Separates liquid and solid waste using a composting medium; no cassette to empty at a dump point. Solids container empties roughly every 2–4 weeks depending on use; liquid container more often. Check local council and national park rules for disposal in your area before relying on it as your only system. Standard on every Sting Air; cassette on the base Sting.
