Fred - Thanks to the link to Bill Abbay's photos. Enjoyed reading his mods.
I neither agree or disagree with what you said. Frankly, I don't know the roof strength of any trailer, at least in a way that can be quantified. My questions were just that, questions. I do know however that all trailers are not created equal. Some have roofs that are stronger than others. Some that I've seen appear to be nothing more than a thin layer of fiberglass without reinforcements or contours to give it additional strength. Others are obviously more substantial with reinforcements, "nogin domes", etc. and were designed to support an AC, storage and/or possibly the weight
of someone walking on it. As for the Bigfoot
roof construction, Bill Abbay's comment seems reasonable; "the Bigfoot
roof construction .... That's more than our stick-built brethren, and very stout when walking on it."
Does anyone know if Bigfoot
used plywood throughout and continuously for the roof or are there gaps in the installation? Also, are there any additional reinforcements, possibly glassed-in spars?
