We have just had our first trip since buying the van, and traveled over some fairly dusty roads around Bourke, Broken Hill etc. Dust entered the van in the top and bottom rear storage areas and around the door. Fixed the door problem by covering the vent with cardboard. On one occasion I opened the dust hatch in the roof as advised and spent an hour at our next camp, cleaning dust off every surface inside. We love the comfort, tow ability, space, etc. seems a pity that an off road van has so many dust access areas. Can anyone help.??
