Ours broke a foot from the mh, it's used so who knows what had happened to it.
And now I have to do it again
A wind gust in Alamogordo NM actually ripped BOTH arms off the mh, one also broke off the awning and landed on the other side in the neighbor's yard
Technically an easy diy, physically fairly hard.
You'll need a ladder (scaffold) to support the awning at the roller end,
AND a E clip tool!
