Avondale roof thickness

[WoodlandsCamper]

Does anybody know the roof thickness of a 1998 Avondale Avocet? I would like to have an Omnivent fan fitted in the central area. The minimum thickness required for the fan is 27mm. I have tried emailing Avondale a couple of times, but have not had a response.

Can't answer the question but would comment that you can "Add" to the thickness quite easily. A neat picture frame like spacer made of flat wood strip or ply painted to match. It will only be a few mm thick after all as the roof must be close to your 27mm , if its short at all.

Fitted inside so as to not compromise the units water sealing.

Thankyou for the suggestion, it sounds a likely way forward.

Remove the inner frame of your skylight and measure it.

Ground to roof height - (ground to floor + floor to ceiling)

easy :O)

Is this liable to break the outer waterproof seal, in case the roof is much too thin for the fan?
