1 pc Fiberglass roof vs. "rubber"; "Huck bolted frame?

Thanks a lot for some really informative answers for me. The positive comments about the huck bolted frame is a surprise as I was thinking a welded frame was the only thing to consider.

As far as fiberglass roofs, I need to see what other manufacturers use them so I have another point of reference.

Rubber roofs (or membrane roofs in general) are immediate turn-offs for me. However, almost all trailers have them unless you go to a place that can make a fiberglass or one piece metal roof. With those, you are not relying on a glob of caulk to keep water out of cracks.

As for huck bolts, I wonder what keeps them from loosening over time. If it can thread on, it can vibrate loose. Maybe put some red Loctite on the threads before putting on the collar and using the tool to mash it down?

Fiberglass roofs are considered better. But by excluding rubber roofs you are going to cull out 95% of your travel trailer choices. You almost never see on hear issues of rubber roofs failing, water gets in at improperly protected penetrations thru the rubber roof.

I would not base my purchase on what type of roof or frame the unit had as the first factor. Floor plan, features, weight, tank capacities would all rank higher in my decision. If then I found two contenders and one had a better roof and or frame, then that may sway my decision.

I have never heard or seen of Venture RV until now. I looked at pictures on line. Nice looking camper. Does not appear to have a cambered roof or gutters on the side but rather is rounded from front to back so I assume all the water runs off either accross the front or down the back wall.

a fiberglass roof wins hands down. no more EPDM for me. that's my first cut when making a decision.

Every time you see long train on the railroad tracks pulling tons and tons of freight down the tracks on the railway cars, transport trailers, auto transport trailers and boxcards...virtually every one of those trailers are made with huck bolted frames. Stronger than welded, simpler to build and much lighter.

Alcoa developed them primarily for use on aluminum Alcoa built chassis and frames, now being used on trucks, busses and general transportion vehicles.

And HuckBolt fasteners meet or exceed the performance of torqued bolts in both shear and tensile strengths. Chances are if your car is 2 or 3 years old it has some huckbolts holding it together!

And membrane roofs are fine, usually having 15 to 20 year warranties...and will likely out last the warranty.

Huck bolted is the Cadillac of frame construction. Also, IMO, the fiberglass is a much better roof than the rubber, and I have had both. The rubber will require annual maintenance and replacement at about 10 years, while the fiberglass is a permanent type roof.
