In order to maintain the Hobby '5-year guarantee for body connections against leaks', the van is supposed to have an annual 'test for leak tightness'. This has to be done by a Hobby dealer (who has to complete a somewhat ludicrous form) and is, supposedly, chargeable. Bearing in mind that this annual test consists entirely of 'visual inspections' that could be carried out by a six-year-old for a tube of Smarties, and also bearing in mind that I will have an independent habitation service carried out beforehand (with measured damp check), what do you reckon would be a reasonable charge? I have tried to find an online copy of the form to be completed by the dealer but failed. Below is the gist of the inspection form: 1.1 State of the vehicle: 'well kept' or 'general wear and tear'. 1.2 Structural changes: yes/no. If yes, list changes. 1.3 Are there visible damages? yes/no. If yes, list damages. 1.4 Is there a smell of decay? yes/no. 2.1 Leak tightness of skylights and windows: yes/no. 2.2 Damage due to dampness: yes/no. 2.3 Leak tightness of entrance door and service flaps: yes/no. 2.4 Waste gas chimney and forced ventilation. Explore the decoration around the roof duct and carry out visual inspection. Have changes been found? yes/no. (My van doesn't have any roof ducts) 2.5 External power socket. Explore the decorative leaf in the clothes cupboard and carry out visual inspection. Is anything objectionable been found? (sic) yes/no. (My van doesn't have an external socket) Any Hobby dealers out there? If so, what would you charge for this cursory leak tightness check? BTW, the first annual check as above was done for nothing by the dealer as the van happened to be back there for one of its many warranty repair visits.
