We didn't get to use our van much since we got it last Fall, but now I'm putting some final touches on for summer camping.
We usually camp in the forest, and like to have a shovel, axe, and bucket for fire maintenance as well as firefighting if it comes to that (small fires). We already had a small shovel, and I found a really nice Gerber axe complete with mounting bracket at Warehouse Sports. The bucket is part of an old Coleman 5 gallon water jug. I found some ATV tool mounting brackets at Warehouse Sports to hang the shovel. I still need to move the curtain hold-back strap to the passenger side, since the curtain won't fit on the driver side with the shovel in the way.
Our extra water jugs are in a Kelty Binto carrier. The other Binto carrier has two Binto's in it - one for plumbing gear and one for electrical gear.
We use the van for skiing, and drying out our ski clothes is always a challenge. Van Specialties installed 2 L-track mounts on the ceiling, and I built a simple detachable clothes rod which puts the wet clothes over the furnace vent. Probably won't want to drive with the clothes hanging, but should be great for evenings and nights.
