I cannot tell you about the nail gun Larry but can suggest if that skirting is mostly down this might be a time to install additional supports. sure it is an investment , just like the double wide. consider running a mini wall behind that skirting. of course the bottom rail being pressure treated wood but a few more staggered uprights to give that skirting some additional support and resistance in the next wind.Lee
