Overview
The Polaris 4 is a 7.4m self-contained motorhome with full toilet and shower, a 130L fridge, and pets allowed, requiring 21. The Double Down is a 6.1m no-bathroom van with pets allowed, accessible from 18. Both sleep and seat four. For independent group travel with onboard facilities, the Polaris 4 is clearly better equipped. The Double Down suits younger groups or those on a tighter budget who are comfortable with campground bathrooms.
