How To Be a GURPS GM treats them as the same. The party of three characters are riding around a wilderness and need to make daily Survival rolls. Their food appears to be treated as part of the basic equipment for the Survival skill. Is this wrong?

At what point do travelers switch from camping to living off the land?

Also, if as a GM, you plan on having campers and people spending the night with all their gear make these rolls or suffer damage, then just tell your players ahead of time so they know to get the skill, and then it is no gotcha.

Hence the need to identify the gotcha rolls.
