My first idea is that those of us who travel the wastes, but fail to call any one place a home need just that, some sort of temporary shelter from the elements when we need to bed down for the night or set up some sort of encampment. Experience dictates that just sleeping out there can be pretty exciting. On one foray, poor Johns awoke to find a scorpion standing in the midst his sleeping party of explorers. Fun stuff! And let me not fail to mention that environmental effects occur even while a character sleeps, so be ready for some health loss and frostbite/sunburns when you log on! So, my suggestion is that a man-portable shelter that can be set up/dismantled be created for those roving wanderer types. It should be light enough that it's not a complete encumbrance to the typical explorer, capable of keeping environmental effects such as sun, cold, and sandstorm at bay, and have a means of keeping the nasties out. Perhaps it's ICly some sort of nanoplastic composite that makes it light yet durable. Additionally, the structure or variants of it should be camoflauged so that those looking through a pair of binoculars or a telescope may only see just another physical bump in the terrain rather than the shelter that it is.
My second idea: either water evaporators or water purifiers. Face it, any water out in the badlands is bad for you no matter how you want to look at it, if it doesn't kill you outright it's going to give you parasites or dysentary. So, a handy device that could pull water out of the environment and deposit it into a canteen or similar would be great, and for those situations when you can't afford an evaporator, perhaps a sanitizer that can be used on water that's acquired from local sources.
Third: Sleeping bags. If you can't afford a shelter, at least get the protection of all-weather sleeping bags. They won't keep out the critters, but they should negate the effects of sleeping on hard ground out in the open to some degree.
Fourth: Basic desert camo gear that should assist the lone wanderer in concealing himself from the prying eyes of standard video cameras, binoculars, and telescopes.
Fifth: For those fully rugged types, the ZMI Stillsuit, meant to make sure every bit of moisture lost is reclaimed for those dusty Fremen-wannabes walking all over the desert on foot, adding a bit of camoflauge and added protection from the elements as well.
Sixth: Sterno, for when you just can't fucking start a fire and need something to cook your rad scorpions and desert rats.
