I have some checkerplate that I'll be putting on the front of the camper and down the sides. The side sections will only be a few inches high but the front will be around 18" maybe taller and cover the full 5' width. Are there the same issues with this as there are with an aluminium skin regarding expansion etc (the plate is 1mm thick). I don't really want to float it there as that means additional trim around it but then I don't want it to damage the ply skin if it expands.
Any suggestions or thought on if this is an issue or not?
Cheers
Steve
