Organization begins at home. Plan what you need and want to take before leaving the house.
Don’t shortchange yourself. Taking items you can use to brighten dead time will pay for themselves.
Plan for seasonal changes of clothing when taking extended trips in spring and fall. Getting caught with the wrong clothing and other gear can make a trip uncomfortable and, sometimes, dangerous. In the fall, winter gear can be a lifesaver in emergencies.
Individual bundles of clothing can make showering simple. It saves rummaging in a bag or drawer when a shower opportunity arises.
Keep logs and other paperwork separate and readily available. Papers thrown on the floor between the seats can cause frustration.
Keep receipts in an envelope or other easily transported container in a place where they can be stashed as they accumulate and be available to you when it comes time to tally up.
If you have a small sleeper, consider keeping your clothing and other necessities up front in the shotgun seat or on the floor in front of it. It saves you from moving everything out of the bunk at night.
