I have several pop ups that I use, and heavy wet snow broke several poles in them over the years.
I figured out a way to stop that. Get a 2x2 piece of wood, cut it to length to fit from the ground to the underside of the hub, maybe a hair long. About an inch below the top drill two holes at 90 degrees to each other and run cord through them, Tie knots in the cord to keep it from pulling through. Then put the pole in place and use the cord to tie it in place, going over the hub. All you have to do is untie it when you get in, tie it back in place when you leave. We haven't broken a pole since. YMMV.
