An RV is a larger vehicle that is suitable for long-term living and can provide comfortable amenities. A camper van is a smaller vehicle that also provides amenities such as a bathroom, kitchen, and sleeping area. Camper vans are more fuel-efficient than an RV. Additionally, camper vans are more affordable and are easier to store when not in use. If you do not have space for an RV, you will need to pay fees at a storage facility.
