In the past, the cheap tents are the first ones shredded in the occasional storms which can bring some serious winds. Also, with proper care, quality tents will last a long time past this trip. At the same time, realize that we aren't backpacking or going into the tundra of the Northern Territories. Cut it just smaller than the floor dimensions of your tent. If yours doesn't have a rating, be sure that it seems heavy enough to withstand the colder nights.
Headlamps are hands free and convenient.
Mini Mag-lites are bright and you can buy a headband for them that turns them into a headlamp. Don't ask to borrow mine, they tend to get lost easily. Your kit should include the usual, Band-Aids, gauze, tape, antibacterial soap and ointment, ace bandages, mole skin, and aspirins. Also include emergency supplies of personal medications. If you're allergic to bee stings, get your doctor to give you an emergency bee sting kit and to show you how to use it.
