I'm sure everyone who has air-camped has a few ideas that might make air
camping a little more enjoyable for others. Here are a few of mine:

Ditch your sleeping bag. Instead, use a combination of sheets and fleece
blankets. Much more comfortable at little or no weight penalty.

Sew an old sheet into a sleeve to cover your camping pad. If you just throw
a sheet over a camping pad, it'll creep overnight and you'll end up sleeping
on the pad itself.

Bring your towels that are almost ready to be downcycled into use for your
dogs or for shop rags. After you've done all of your showering for the week,
use the towels to wipe down the aircraft, then put the towels in the nearest
dumpster.

Underwear. Same as towels. Take the stuff that is almost ready for the
trash heap. Wear it, then trash it. Alternately, leave it at the ANN booth.

Use a soft-side cooler as one of your travel bags. Fill it with clothes on
the way to the show, then unload it and use it as a cooler until you leave.

Take earplugs. Not everyone is on your sleep schedule, and there is always
someone loud within earshot. In particular, there is no way you're going to
get the slightly drunk group at the *next* tent to keep it quiet for more
than 5 minutes, so you might as well try the earplugs.

If you're a nighttime reader, flashlights using LED bulbs are your friend.
100+ hours of battery life, so you don't need to bring a sleeve of AA
batteries in order to pour through all the literature you picked up during
the day.

Not a camping note, but applies to all fly-ins: Don't power your airplane
out of its parking space in back to back rows. Pull it out, turn it
perpindicular, then fire it up... There are few things more aggravating
than having the control surfaces on your airplane bashed around by some
thoughtless clown.
