Is the 4000 Express House/Foredeck Cored?

[MC1600]

Does anyone know if the foredeck on the 4000 Express (1999 if it matters) is cored or solid fiberglass? I’m talking about the area forward of the windshield, by the bow pad. When I had my headliner down last year I thought for sure I saw the underside of bare fiberglass but can’t remember for sure. Figured I’d ask here if anyone knows. 

Thanks!
