Getting a second battery is a good call, dedicated space for water. You'll probably end up carrying more stuff this time around. Tools for the vehicle, fuel.

Doesn't your van have rails? If you had aftermarket rails you could pick them up anywhere and just drill a hole in them and use a pair of gate bolts to pin your panel on. Idk if you'd want one panel or two small ones, I'm just thinking whether you could store the panels inside the van if you needed to. Like if you were in an urban area.

I've seen a lot that employ the milk crate storage system
