Cost of RVing
Of course there are costs associated with RVing but these costs are, for the most part, different from those you incur while living in a house, apartment, or condo. Think of RVing costs as categorized into the following... Campground Costs and Traveling Costs. Plus, there are discounts, too.
Campground costs include the cost of parking your RV overnight. It could be just one night (when traveling across the country) or several months (like a snowbird). You must park that RV somewhere each night. It could be there's no cost (called boondocking) or the cost of a campground. Regardless, if you do not own the land where you park it, then you are renting a parking space for some period of time or you have permission to park free.
Traveling costs are just that, the cost of driving/moving the RV to somewhere. It is REALLY rare that someone would use an RV as a permanent structure and not move it occasionally. The most common cost is fuel but there are other costs, too, such as maintenance, repair, and even driving costs such as tolls.
