My husband doesn't like to take alot of comforts of home. First he simply doesn't have the room in his packs.
He takes his portable dvd player and a packet of movies. He takes a picture in his wallet. I mail him the digital picture frame later on.
His important things are snack foods and comfortable underwear to be honest.
I usually mail him somethings when he gets settled like bedding, comfy pillow, some books, and his coffee pot.
I'm telling you they have to pack the most crazy things and there is NO room in all those bags for anything else. The bags get tossed here and there and schlepped all over and my husband simply didn't want to keep up with alot of stuff while traveling.
