Questions about RVs?


What type of RV should I choose?


Start by determining how many people are planning to travel with you. Going on a solo-journey? Choose a camper van or a teardrop trailer. Bringing the whole family along for the ride? Consider a spacious Class A or five-wheel.

You’ll also want to consider amenities. For example, if you’re planning to cook on the road, you’ll want a kitchenette. If your campground doesn’t have public restrooms, you’ll want to search RVs with bathrooms. Check out full descriptions of our models to help you decide here.


Do the RVs have bathrooms?


Yes. Class A’s, Class B’s, and Class C’s and five-Wheels typically have bathrooms. Depending on where you plan on camping, you’ll want to double-check the availability of restrooms if selecting a rig without a bathroom. Nervous about renting an RV with a bathroom? Owners can help show you how to clean the tank or will offer to do it for you for a fee.


How does check-in work?


Once an Owner approves your RV reservation, you can coordinate a time to pick up your rig or have it delivered to your doorstep or campsite. At that point, the owner will do a key exchange with you and walk you through the RV and answer any questions you might have.
