Cheeky V is coming together nicely now and after all the work I've done on the body (and after taking all of the insides to the tip) I decided to give her a completely new interior but I'm stuck as to what wood I should use for the base of the bed in the roof (the bit that gets covered in the middle where you normally stand up)
Any ideas welcome

I'm using 12mm Ply for the majority of the it but this flex's to much and will probably just fall straight through
Cheers
Cheeky V
