That's awesome. Having a van for surfing is a game-changer. I bought my van (1991 E350 Super Wagon) last January and it completely changed my routine. Just having some space to get out of the wind while you pull on your wetsuit is such a luxury. My van is nowhere near as nice as yours but it gets the job done haha I thought about doing a conversion but my rig is already where I want it for my needs: hauling longboards to the beach and towing my boat. The plan is to upgrade to something 4x4 with a higher roof eventually.
