This quest is just a repeatable version of this one: https://classicdb.ch/?quest=1707
When I completed this quest, I didn't get any experience - only the 10 reputation with Gadgetzan and the care package, but it's still a great side quest to be doing while you're doing the Wastewander Justice and More Wastewander Justice quests (https://classicdb.ch/?quest=1690 and https://classicdb.ch/?quest=1691), since some of the Wastewanders you kill there will drop the water pouches needed for this quest.

Oh, and this quest is also a nice way of grinding a bit of reputation with Gadgetzan while you're in the mid-fourties since every Wastewander you kill will earn you 5 reputation and this quest earns you 10 reputation with Gadgetzan.

This is a great way to stock up on pots. The GOOD ones. I have found grinding on the camps in this area to be lucrative. Cloth, coin, Good Drops, Recipes,xp, and these pouches. I have easily turned in 100+ AND HAVE A GREAT STOCK OF Healing, and Mana pots from the rewards.

dont know why this quest is on search twice but

i have been doing this quest regularly because its breeze and it gets you the good food/water/potions for FREE. the water is common drop. after first time you'll only get 400xp from reward, but you can do it as many times as you want. he always gives 1-3 food, 1-3 water, sometimes a supperior hp/mana potion, and rare, but sometimes a random scroll. I just did this quest twice today, he gave me food/water and an hp potion, second time he gave me scroll of intell3. this quest is great to farm for some good food/water, its fast and free. take you maybe 10-20mins to get 5water drops. this is the easiest and fastest acess to the good food/water for as early as it can be done. after doing this quest only around 8 times maybe, i have over stack of food/water, and bunch of potions, and it took very little time. you no longer have to save your food/water for the most usefull times. the bonus is that you can do this quest while you are doing the other quests that involve killing the bandits, the named bandits, and getting back a guys stolen something in fort, by time you get those done you'll have around 10+ water drops.

but watch out for the one named bandit SE of town, he has 2 stealthed bodyguards and wanders around. if theyaggro while you fight you get 3 adds, and hes lvl 46.(everything else is 42ish)

According to my information this quest is a way to build repeatable repuation with Gadgetzhan. Is there any definitive answer on whether I am correct in this...

Yes, this quest just for get reputation with Gadgetzan. It's repeatable, so you may take it until you get revered reputation.
Only one little question remains ... what for that reputation, what it does? Maybe there's special items sold by Gadgetzanians?

i handed in 15 out of 17 of them, and i got a total of 9 moonberry jucies, 6 moon harvest pumpkin, 3 superior mana pot and 2 hp pot. perfect. love this quest. though i didn't really see the xp though. lvl 45
