AUTO BILD Reisemobil tested four dry separating toilets for camper vans from Boxio, KoMa.land, Trelino and Trobolo. The comparison covered sitting, separation, emptying, carrying, disassembly and cleaning, with a separate male and female assessment. The Trelino Evo L scored 4.5 out of 5 stars for its wide seat, reliable separation and easy cleaning, but was bulky and hard to grip. The KoMa.land Kackbox had a narrow seat and was difficult to clean, the Trobolo WandaGo had a small seat and urine splashes, and the Boxio Toilet Max+ showed separation failures in the practical test and an unwieldy urine canister.
