I'm not sure I can limit it to 3, but I can condense into categories:

1) Van stuff: parts, tools, extra PVC strut braces to give away,
maps, list of VW shops, extra copies of LiMBO's Transporter.

2) Camping/comfort/fun stuff: food, books, games, porta potti,
collapsible chairs, table, Coleman stove, propane lantern,
small generator.

3) Emergency stuff: fire extinguisher (2), AAA card, credit card,
cell phone, MREs, H&K USP .45 or East German Makarov (where legal).
