Slowcowboy,
You sure do have the worst luck. I've not camped in Colorado enduring a freak wind gusts, experienced any strong Santa Ana winds, or never have had the pleasure of ocean front winds with our setup.
In my experience I figured it was rather secure against winds. I mean as compared to an first-up type shelter. If the mounts are solid the nylon would flap but I would never have bet on the total destruction you are describing.
We did experience an issue with heavy rains at Spring Mill in Indiana last May. Here is a photo from Saturday morning - I almost didn't get the door open. I apologize for the poor photo as it was rather early and it is from my phone.
This just shows one side but both sides held about an equal amount of water. I would guess about five gallons on each side of the main support pole. That is a lot of weight. You can see the rods are bowed downward due to the weight. They never disintegrated nor did the plastic bits fly all apart.
I haven't come up with a solution to this problem yet - perhaps some fiberglass poles to get an arch upwards so the rain would drain over the horizontal rails.
One difference may be that on our trailer the supports are right at the ends of the shelter - 10 foot trailer with the supports about 4 inches from the ends.
Just the darnedest luck I tell you!
