Whenever the need arises to buy a fellow Jeeper a present, I usually try to find something that they can use for the Jeep but not necessarily a part that goes on the Jeep. Knowledge is a wonderful gift. Jeep books, magazine subscriptions, a factory level service manual. How about a set of tire deflaters and a nice pressure gauge? How equipped are they in the tool department? Maybe a nice set of Torx bits and sockets.
