Advice on replacing exterior siding

[BGR]

My 1988 Tioga Arrow had a water leak on the cabover bunk and I am trying to rebuild the cab myself. In taking out the plywood floor my "helper" cut into the siding that was attached to it and now I have like a 6" tear in it that must be repaired. At the same time, I want to eliminate the front window as I believe this was one source of the leak and it will make this an easier job, but to do that I have to replace the siding instead of repairing it.

The question is, I have no idea what kind of material the nose siding actually is. It is the corrugated style and looks like fiberglass to me, but I'm told the corrugated siding is always aluminum and the smooth siding (filon) is fiberglass. Any one know what they were putting on Tioga Arrows in those years?

I called Fleetwood service/parts and the guy actually couldn't help identify the material, but he did say I would not be able to find a source for corrugated fiberglass siding and would have to go with smooth siding to replace it. Pointed me to all-rite manufacturing. Does anyone know a source for the corrugated fiberglass siding, pre-painted? While this camper is not a real looker any more, missing smooth and corrugated siding will probably look very odd. I found a source for aluminum siding, but nothing for corrugated fiberglass.

This is actually more job than I wanted. Interesting to see how they construct these and I am happy to save a $3K in repairs (one estimate I got) for an RV worth like $3K (or less,) but it's a rather complicated repair. The problem was once I peeled the skin back big chunks of wood starting falling out and being curious I probed further. I got to the point of no return!

Go to: New and Reconditioned RV Parts & Accessories - RV Surplus and look under 'Repair Parts'-> 'Fiberglass Siding'. They should have what you need. I'm taking care of the delamination on my Coachmen, and they have the best prices and service that I've found so far.
