That's a pretty broad range. You definitely want shelter, water, water purification, some sort of way to cook, knife, multi-tool, saw, warm clothing, means to signal, communication gear, navigation gear, first aid, light, fire-building, etc.

I think comparing it to a load someone would go backpacking with over a weekend would work well. You're already carrying a sleeping bag, tent, ground pad, warm clothes, food, water, stove, clothing, and emergency equipment.
