Rubber Membrane vs Fiberglass Roof

between rubber and fiberglass/aluminum. I would consider buying a unit with a TPO roof, wouldn't want another rubber one.

So what catagory does the TPO roof fall into, good / bad?

I'd be more concerned about buying a former rental than worrying about the roof. Just think. Most of those renters have never driven an RV before. And some wouldn't admit to anything that didn't show when returning it. I know that I made some mistakes at first with my new 'C', and some of them were expensive.

we are looking at sunseeker 2300 because its available on chevy and seems to be best made of the 3 brands on chevy.we like you want no slides,but for leaks possibilities but the stiffness of unit makes even more sense .

For what it's worth, my 2005 Itasca's Class C brochure shows the same SuperStructure diagram, so Winnebago has been using that construction technique since at least 2005.

Also, we went for a no-slide model so as to help maintain coach framing stiffness and thus reduce coach structure stresses when on the tilted roads we run across when off the pavement rockhounding/exploring/fishing with our rig.

Itasca sounds like certain models and floor plans?

Combine these features with all steel framing and you have one very well constructed coach.

What you're saying seems very similar to what Winnebago talks about they do here:

We have a 2012 Nexus 23P and yes, the one piece fiberglass roof does go over the sides. Also the front and rear end caps are one piece and all of the windows have automotive seals. Combine these features with all steel framing and you have one very well constructed coach.

All fiberglass RV roofs may not be the same.

You want one that's all one piece - instead of being flat fiberglass sheets with seams on the roof between the flat sheet edges.

You want a fiberglass roof that has a crown in it - not flat.

Also, you want one that has it's edges - at least all along the long side runs of the coach - rolled over 3 or 4 inches so no 90-degree seam is present right at the roof edge where rooftop fiberglass meets sidewall material.
