Thank you Sven. 18mm finalised.

Pictures please.

Thank you Bob.

I am planning to use structural ply but not sure about what thickness to use. At home we have a single bed which has like 12mm ply and it is coping really well.

So wondering if 12mm ply will do the trick or should I over engineer as you said and go for 18mm ?

How do I do stress ...

hi All,

Just bought a bongo 2002, petrol 2.0;

It has an aftermarket lifting roof( manual). But the roof floor panel is missing. Question is can I use the OEM floor panel from a older bongo or what material can be used as a floor panel? will something like 15mm dual side ply work?

Many thanks in ...
