Excursion checklist (PDF)
This is the document I use prior to any excursion (one night trips or multi-day excursions).
I do not pack all of these things as different trips require different materials, but it helps me identify needs for a given excursion.
I find it very helpful and can now pack in under 10 minutes.
Camp/Bike Inventory & Maintanence Log (PDF)
This is the document that I use to track my inventory and maintenance.
Making quality gear last requires care and upkeep, so I try to keep an accurate maintenance log of problems, repairs and so on.
