He was very despondent about the whole situation. He had put a ton of work into the trailer, and was planning to do the interior in the spring.


Brevi tempore!

Just think about physics. Most likely the middle rib near the a/c unit went beyond its tensile strength and stressed the rib out until a catastrophic tear occurred. That then distributed the displaced load onto the adjacent ribs. When that happens they will fall like dominoes. Provided evidence in the background suggests around not just 2+ feet of snow but ICE also (far more dense). If that powder is actually snow holding water (slush) it could be even heavier. I would imagine that there is close to a ton of weight placed on top of the trailer. Its kind of like that funny mayhem commercial....

It makes sense. Without the inner skin the ribs are allowed to twist. As soon as they do their strength is gone. I don't know about on a newer trailer but on my '63 the ribs are very flimsy. I can twist them with my hand (yes my inner skins are currently out).

Well in Texas I am almost positive you will not see that situation.

I know i'm sounding like a "Monday morning quarterback" but you would think maybe to brace the exterior shell from within, via jack and lumber. That would have crossed my mind well before that happened. But what am I saying, that's probably Canada where they get that in a days time. I still feel deeply saddened for this owner, man I could not even imagine what I would say after walking out and seeing that sight ..... Man

Interior skin necessary?

I see it happening as the weight pushed down primarily on the center of the roof, pushing the sides outward at the base of the arc of the roof, once the walls moved outward a certain amount it was game over, the roof fell in a rapid cascade effect starting at near the center of the roof.

These trailers are strong because of the arch, and most of the strength comes from the outer skin, (the ribs main contribution to strength is holding the skin in place), once the arch is compromised, it is done.

I am of the opinion that inner skins would not have helped to prevent this as much as the wall bulkheads would have.

That said, my trailer has only one wall... Very near the back of the trailer.


Brevi tempore!

Agreed, he should have done some preventive measures before this happened. Though the skin does indeed give strength (not more than the bulkheads), it will not overcome mother nature to that degree.

I assert that there was SEVERAL thousand pounds of crystalized water on the roof of that trailer.

Right, it was spring and raining into the snow. The owner was out of the area for awhile and found this when he came home.
