Overview
The Mighty Duo adds full bathroom and self-contained certification to a 5.9m two-person layout; the Highball is a compact 5.5m no-bathroom option. Both allow pets. The Duo requires 21; the Highball opens from 18. For younger drivers, the Highball is the only option in this bracket. For older travellers who want bathroom independence, the Duo is the practical step up without a large increase in vehicle size.
