I live here in Okinawa and 90% of all dive here is from the shore, most of us have Toyota Surf 4 runner. I still have a small Nissan Silvia 240 SX. The other day I was given a Toyota Hi Ace van from a friend it is the largest van Toyota makes. I think it will make a good dive van. It has descent ground clearance way better than the Silvia, for getting down some of the bad roads to the dive site. I have taken out the back seat to make room for tanks and dive gear for me and some friends. Besides a tank rack and a pole to hang stuff from one on the back door when it is open and one behind the seat. What else would you recommend to add? It will be uses for day trips holding four divers plus and 12 or more AL 80s.
