My wife and I had an incredible trip with this van! Hard to imagine there being a better, more cost-effective way for two people to explore the beautiful island of Oahu. The host was extremely helpful and responsive, and the van was pretty easy to drive and maneuver. It does have a GPS system and USB phone hookup which was nice for hands-free navigation and tunes while on the road. All appliances including the kitchen sink, stove, fans, and solar-powered charging system were quite functional and easy to use. Special shoutout to the host for the provided cooler, towels, and beach chairs - so useful!
We spent most of our nights sleeping at Malaekahana Beach Campground as others have mentioned. This was a great spot and served as a perfect base camp to explore different hiking spots and beaches along the North Shore. Would recommend vehicle camping site #5 as it had an ocean view.
For surfers - in case it isn't clear from the photos, a shortboard/fish can pretty comfortably fit within the extra space in the van without much hassle, but for any board longer than a mid-length I would suggest just renting a board at the beach (or campground!) to maximize van space.
Overall, I would HIGHLY recommend this listing to anyone interested, especially if you have an interest in or experience with car camping! We will likely be daydreaming about this trip for years to come.
