60 to 75 MPH winds are not uncommon in the mountains of CO. We've never cranked down the PUP body for wind, and we've been through several nights that were so windy we couldn't sleep.
On the awning:
When our bag awning was retracted, we one time experienced winds so strong that the wind would repeatedly lift the bag and then SLAM it against the roof. It really shook the trailer. That was unnerving enough that I installed some 2" wide industrial velcro between the bag and the roof body...during the wind storm.
I put 18" strips of velcro on either end of the 13' long bag, and that was enough to stop the banging.
Our high-wall PUP is also lifted for off-roading. So, when we determine to deploy the awning, it's kind of a one-way decision. It would be nearly impossible to put it away without lowering the roof...especially in high winds.
I'm 6'6", and I have a 3-step aluminum step ladder, but I can barely reach the awning when the roof is up - especially when setup on the shores of our favorite lake where the terrain slopes toward the lake so much we often have to BOTH dig a hole for the uphill wheel and raise the downhill wheel 4" to 6" on blocks to level the trailer.
So, instead, I guy the awning to the ground with heavy duty stakes. 60 to 75 MPH winds would surely destroy it, but thus far, we've survived high winds (and hail) around thunderstorms with no damage to the awning. I use parachute cord and steel tent stakes with the plastic t-caps to hold the guy ropes and the legs of the awning.
If we know to expect high winds, we don't deploy the awning, but if the awning is out, and we know we must put it away, we'd have to remove the door, remove the safety braces, close up the bathroom, and lower the roof most of the way in order to roll it back into the bag.
Not sure if this hail video will work here, but if it does, the guy rope shows as yellow when I pan left during the hail-storm.
