Our experiences with the van were awesome. We met with Keiran whom explained everything you need to know about his van. He also provided a manual about the van, which makes everything so much easier.
The van has everything you need. I will only recommend to bring a mini fan with you, as in it can get really hot if you don't open the window at night when you want to go to sleep.
And for more better milage, drive the van around 80-90 km/h and lose the water from the cooler to reduce to weight you're carrying.
Keiran also suggested us the best places to go. We initially decided to drive from Sydney to Melbourne but Keiran said it would cost us so much time on the road, so he recommended Seal Rocks and Coffs Harbour. I definitely dont have any regret following his advice. The scenery was absolutely breathtaking.
Overall, Keiran is a great host and I would totally recommend it to anybody who wants to explore Sydney differently. We sure be looking for Keiran next time we want to do another road trip.
