Clean and refuel the vehicle
Always clean and refuel your van before returning it, as most rental companies will charge additional fees if you don't.
"You'd be amazed at what people leave in trucks," Howell says. "Sometimes it's really disgusting."
How clean is clean enough? Howell says a good rule of thumb is to return a van as clean as it was when you picked it up.
Most firms also require you to return the vehicle with the same amount of fuel it came with when it left the lot, usually a full tank. Otherwise, the rental firm will typically add a "refueling fee" and charge you above-market prices to refuel.
