Coming up on 23 years of owning our unit. It came with a mounted spare. Only had a need for it once in all those years. Let me tell you we will never be without it. Happened less than a week of replacing all tires, brand new tire went down slowly on a county road. Tow service spent over an hour trying to find a tire and rim, even though we told them we had both. He had no luck came out with a huge tow truck was amazed we actually had a good spare. He said his experience with campers was not good, usually spares and rim didn’t match what was on the unit. He had it changed in short order. The reason brand new tire went down is another CW story for another time.
