Well, this is just one of those necessary annoyances of RVing. Yes, you must spend money to get where you are going. Even if it is just fuel, it is generally more expensive to take your RV where you want to go, rather than just driving. And then of course there’s general maintenance. If you own a motorhome you have a drivetrain to look after. Tires to buy, etc. But those costs are generally not much more than, say, maintaining your daily driver.
And there are other expenses which you may not think of. Camping is a big one. It is not uncommon to spend up to $100/night or even more, for some of the high-end RV parks. But in our experience, most campgrounds are roughly ½ the cost of, say, staying in a hotel room for a night.
We recently got back from a few nights camping and it was about $65/night for a fully serviced, level, pull through spot near the beach. Not bad considering how popular an RV park that one is. It was full too, despite Covid-19 warnings, but from what we saw people were safe distancing.
But if you want to save some money, you don’t have to stay in an RV park. Boondocking is a great option. That is where you find a place of bare land and park there. There are no services, but there may also be little to no cost.
If you are new to RVing then the costs may be even higher. While new RVs come with a power cord, some don’t have water hoses or sewer lines. You also usually don’t get your “staples” – dishes, pots & pans, blankets & sheets, bathroom essentials and so on. So, you have to either move things from your home to your RV, or purchase a second set of what you need. The good thing is second-hand stores and garage sales are great places you can find those things you might want to keep in your RV.
