Hi all, I'm doing a hardside pickup camper with a roof and some parts from an old vintage city bus. I'm looking for a place online to buy composite wall panels and extrusions. I looked at Total Composites, but it does not appear that they deal in low volume. Anyone have an online source that ships 4'x 8' panels or is there another product that it readily available, special order or not, from a big box home center? Corner Extrusions? Can anyone help? Thanks.
