Don't want to jinx you on flat tires, but make sure to get the block that you put in front or behind the tires. You pull up or back up onto the good tire and then fix the bad tire. So much easier than a jack. Lot's of little things you will get down the road. Never move over onto the side of the road for people to pass, that's where you pick up the bad stuff. Ask me how I know.
You're not a true-RVer until you have a blowout. It's not if, it's when.
