RV living gets marketed as the ultimate freedom lifestyle—cheaper than rent, simpler than homeownership, and the perfect way to escape the daily grind. But here’s the truth nobody tells you: that dreamy road trip can come with a price tag that’ll make your jaw drop.

For every 100 pounds you add to your vehicle, you lose about 1% of your fuel efficiency. So ditch the unnecessary weight—yes, including that collection of “just in case” items gathering dust. Empty your freshwater tank before driving an
