We received the new rooflight within the scheduled delivery time OK. Fast service

It came in a huge brown cardboard box - inside was the rooflight itself unboxed with no transit packing or fitting instructions. Finding the manufacturer's instructions on the Internet it turns out there are two different depth sizes of this particular model of rooflight, depending on the thickness of the caravan roof. There is no reference to this when purchasing or any option to choose which one you are getting. This appears to be a common issue across the industry. We've got the wrong one but as it fits the hole in the roof I have "customised" it and it appears to work OK - time will tell.

Yes it was the model, but more should be done to make customers aware of variations within a model and for a brand new item I would expect to see it in the manufacturer's box with fitting instructions (as on the shelf in the local caravan service centre). Mind you who would keep the box anyway...

This supplier is now aware of the issue and is actively looking at what can be done - that gets my vote every time. Well done to them for following through.
