Depends on how you are traveling. If you have room for plenty of stuff, the skies the limit. Self contained I have a thermarest and a two man tent. On our bus for Rabgrai, I have a four man tent and an air mattress. I’ll take the comfort any day. If you are using an air mattress, test is out ahead of time to make sure it doesn’t leak. Nothing worse than waking up that first morning lying on the ground.
