Jonathan and Stephani’s van was perfect for what we were looking for - I would have actually loved to stay for more than just two nights just to be able to explore all of Oahu. Check-in/check-out was seamless - you meet at their house and they will go over everything with you. We camped at Maleakahana beach campground for two nights, which is technically the only sanctioned van camping that there is on the island (at least that we could find). Jonathan and Stephani do give other suggestions in their van guide handout so I would recommend looking at those.
The van had everything that we needed - mosquito net was great to be able to camp with the doors open and let the cool breeze in at night. All other camping gear was provided too - stove/gas, cups, plates, etc. Note that the cooler is small so you will need to buy a disposable one if you’re planning to prepare actual meals - we just stuck to bagels and coffee in the morning.
Mahalo Jonathan and Stephani! 10/10 experience.
