Thanks Tooks. The pictures on the website weren’t that clear. Best to get advice from someone who knows 😊Take the removable floor level out (the bit you lift up to access the underfloor area) and what you’re looking at is the lower floor, with the wheel well in it.
If you want a liner that sits on top of the removable floor, that’s the raised floor.
Twi different shaped liners depending on what you want to line?
