I sent out a level 50 Mr. Burke and i was aiming for over 60 hours, but I only gave him 13 stimpacks and he had used them all up (and not a single radaway) by only 36 hours. I got him returning, sent out bittercup in the meantime, and when burke gets back im gonna send him with as many stimpacks as i possibly can and try and leave him for a week or so. He's got two rare guns on him right now, but they are both superior BB guns or something, which is pretty lame. All the rest of his gear is standard, and he's got 6k in caps on him.

On a side note, do people out in the wasteland count towards resources being used? I was wondering what would happen if i sent out all 59 of my dwellers into the wasteland, could my vault be able to stay without using up resources? That would be pretty cool.

Pre-patch (beause of DeathClaw attacks) I use to keep 30 or so out in the Wasteland. All where level 50 and had maxed SPECIAL, gear varied due to the number going out. I would send them out with 25 stims and 5 rad (sometimes they never even used one). They usually stayed out 3.5 days before I would recall them. Sometimes they would die because I would forget to check on them or it would happen while I was sleeping. But the caps they brought in more than paid for their revive.

Post patch. I had to restructure my entrance and pulled all my wanderers in. Now I have a kill path that keeps 10 dwellers useless (ties up my best armor and weapons.) I moved the maxed SPECIAL dwellers into production rooms to get stims/food/water/power faster. I have slowly built up more maxed SPECIAL dwellers and I am using the Wasteland to level them up to 50 really fast. The new batch of wanderers are staying out almost as long as the old batch but not quite. The gear they are bringing in is varied, mostly crap but a few good pieces. One dweller didn't bring back anything that I wanted. Sold all of it before he came into the vault. But at least he leveled to 50 and I loaded him up with stims and sent him out again. Total rotation on new group is around 17, working back towards 30+.
