Do you carry a spare tire for your Class C?

I do have a spare but now that we have been talking about them I have no idea if I have a jack, I will have to look into this. I do have roadside assistance and as long as I am off the road I would be okay with waiting awhile as I do have everything with me that I need. I would not starve and I have a bathroom so not a huge problem.

I know many guys that carry the liquid tire repair to inject into tires. I always thought this was a bad idea but a lot of expedition people have started to carry a can or two with them. I am thinking of doing this but have not convinced myself yet.
