I think someone mentioned roadside assistance. That is if you plan to have some. Perhaps it came with the purchase of your RV? If not and you plan on getting some, then I would budget about $150/year at least for it. If not, then you might want to budget in your own personal savings account for it. Just to give you an idea, if you don't have an inflated spare (meaning spare already mounted on an rim), then roadside is going to charge you $150, to mount a spare on one of your rims. Then if you don't have a spare tire with you, they will charge you a higher price than you normally would pay for a spare. So if you have no spare at all, then expect roadside service to charge you about $400 or so to get you going again. Of course if you call someone yourself and skip the roadside service, you can do it a little cheaper. But if you have an inflated spare, roadside service won't charge you anything to send a truck out to you to change the tire.
