Having a level camper van isn’t nearly as important as other types of RVs since Usain’s refrigerator doesn’t run on propane. As long as our heads are higher than our feet when sleeping then it isn’t that big of deal so most sites are level enough. There have been a couple of times when a couple of inches higher in the back was needed so it was nice to have these leveling blocks on hand. They are also useful for other times when we need an extra step or to prop something up so the space they take up in Usain’s “garage” is worth it.
