This is possible however, it depends on the type of tent and roof rack. If your tent is a Duö, the rack may or may not have a ridge. If your tent is a Quatrö or a Family, the rack should not have a ridge that would interfere with the opening of the tilting floor on the right-hand side. Moreover, the bars must not be too far apart, nor too close, in order to be able to secure the NuFix fastening system. Do not hesitate to send us photos of your roof rack so that we can help.
