Mount on 10' steel pole?

I found a nice 1"x10’ steel pole and mounted it on the back of my rv. Inziptied it to ever step making it as stable as possible. But with pretty windy out and i see some play in the pole. Not much but i cant imagine being able to keep any pole steady that high in 15mph winds. Is that going to work for accurate numbers?
