What you won't generally get is a deep freeze during the open dates, but it is not a sure thing. With very few precautions (unhooking and draining your water hose, keeping any plants inside) a rig should have no problem with a few hours of temps in the upper 20s. Personally, the benefits of an early or late stay in Yellowstone would far outweigh any concerns about cold temps.
May 10 - Sept 22 are the days of operation. You're not likely to freeze during these dates.
