Ok does the Winnebago have the best roof system

Under trees, whether driving mistakes or falling limbs, what rips fabric can still be just a scuff-mark on the heavier Filon sheeting. It is not as heavy as a molded fiberglass cap (e.g. used on upper end Newmars) firmly backed up by being sandwiched with a foam core.

It eventually fades, discolors, but is unlikely to weather through in a human lifetime. Advantage over a comparable aluminum skin is no corrosion of the plastic.

But Winnebago is not the best made rig. It is a rig made to a range of mass markets, with the advantage over some competitors in the same price ranges of partially automated productions and a formal quality management system. "Best made" usually implies "cost is no object" and Winnebago does not build for the market category where prices start at $800K and go well over $2,000,000 so every piece can be the best available, everything carefully hand-crafted.

its really one AND the other

I had a travel trailer for 8 years that had the epdm rubber roof. It never gave me any trouble, but it did seem vulnerable anytime I was up on the roof to do things like install vent covers or whatever. Always felt like I needed to walk carefully and not accidentally drop a screwdriver or other tool. It also seemed very prone to get that dark maroon colored mold or whatever it was, needed cleaning a lot if you cared about keeping it clean. I have a Winnebago now with a fiberglass roof and like it much better. I can walk around on it and it feels solid and secure, I don't worry as much about accidentally dropping something, I don't worry about hail or low hanging branches damaging it, and it seems like it stays cleaner. But, having had both, I would see having a fiberglass roof as a bonus, but not a necessity. I wouldn't let the roof material determine if I bought the rv or not, other things are more important (floor plan, quality, price, etc.).

So, longevity vs leakproofness? Definitely can see that as advantage.

What percent of rubber roofs leak through failure of the rubber vs seal leaks at protrusions/cuts in the roof? Does fiberglass help prevent leaks in seals at protrusions/cuts?

I'm not trying to argue or debate but truly curious...what makes a fiberglass better than rubber?

do a search in this forum on folks wondering what to use to salvage their rubber roof. of course any seams/joints can leak if improperly sealed.

any fiberglass roof will be superior to rubber and probably TPO.

I have no intention of placing a second motorhome on the roof. So, whatever.

But, think of all the beer you could carry on the roof. :)

And that is YOUR opinion. I own one that has been relatively problem free but still agree with you. That still doesn't make it true or false
