    Practical ownership tips

    Licence requirements

    At 4,500kg GVW, the Knaus Sun I exceeds 3,500kg and requires a C1 licence (or a pre-January 1997 car licence). Confirm the exact GVW with the seller before purchase.

    Payload capacity

    The Knaus Sun I has approximately 800kg of user payload for passengers, water, gas, and personal gear. Check the actual plated weight against the unladen weight for the specific vehicle you are viewing.

    Before you buy

    Request a habitation check for any used unit. Check the base vehicle service history, MOT record, and whether the V5C matches the seller. For conversions, confirm the vehicle is correctly registered with DVLA.
