When considering one-way RV rental costs, one of the first things you should be aware of is that a one-way rental will typically cost a bit more than a round-trip rental. This has to do with logistics since rental companies need to manage how many vehicles they have at each location, and one-way rentals can cause some difficulties with that aspect since you drop it off in a different location that where you picked it up.   Otherwise, the main costs associated with one-way RV rental are: Daily fee: The daily rate you pay to have and use the vehicle. Mileage fees: How much you pay per mile you drive.  Gas: You’ll need to keep your vehicle fueled up during your trip, so determine the vehicle’s gas mileage. Our camper vans at Escape get an average of about 15.5 MPG, making them on the higher end of the industry.  Equipment: Think about any extra camping equipment or accessories you might need to buy for your trip. Those could be things like bedding, shade umbrellas, dinnerware, or first aid.    You can save on costs by planning your route to avoid driving unnecessary miles, turning the van off when you aren’t driving to save on gas, and cleaning it before returning it to avoid cleaning fees.
