Rubber Membrane vs Fiberglass Roof

[fbn_ent]

I am still looking for a Class C and have found that the Forest River Sunseekers available used (rentals) have fiberglass roofs. Can you folks give me some input as to which is the best option? I would think that fiberglass is a big plus but I'm new to this world...:@
Thanks

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

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?

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.

would the nexus or sunseeker be a better fiberglas roof construction?like all 1 piece.

I miss the days of one piece aluminum roofs. I don't remember older trailers turning into scrap in five years due to water intrusion like ones made in the past decade tend to do.

The general problem is that unless properly engineered, the caulk in seams tends to be the only thing protecting against water intrusion, especially with water coming in at 70+ MPH while on the road. The two best cures are either the rvroof.com epoxy spray (so the roof is covered with a one piece coating), or if one does a good job (and this is not easy) of using Eternabond with all seams, making sure it is well pressed down and into place.

WOW! Great info. Special thanks to ron.dittmer. The only MH I have had is my home built 30' Bluebird school bus and I inspected the additions (holes) in the roof often. (Call me paranoid!) I want to buy a used unit to be ready to go in late Feb / early March so I will be looking at quite a few. Have looked at e-bay but have an issue with travelling all over North America to view them....
I will definitely be having a close look at the Sunseeker that is available.

I have an aluminum roof on my Telstar class c nearly 20 years old. No leaks
