The roadways are rough, it's not unusual to lose one now and then. Ten of them suddenly breaking loose is excessive and a symptom of out of balance running gear (tires, wheels, hubs), or too rigid sway control bars connected to a too rigid suspension on the tow vehicle if you just changed either one or both.
I would start by rebalancing the tires if all else has been the same since Airstream was new, then look into reasons for excessive vibration.
