That is true. Like with one of the donut spares, you should only drive slowly to the nearest garage. In addition, jacking up your RV in the rear and taking off one of the two tires and then jacking up the front to take off the front tire and replace it, is not something that I would ever want to do. The chance of damaging your very expensive toy or yourself is just too great - at least for me. Much better and probably cheaper in the long run to call a tire guy and have him come deal with it.
