Ok so I'm thinking of attacking the Tribal Village at LV2. I plan on attacking it from above which will waste a lot of bullets but it will be worth it to get stuff like the Fire Axe and Raider Armor. My question is this how far away do I have to save so that if I don't like the items I can reload and try again. Thats basically my question because I don't wanna attack the Cazadors then head down to the village and find out that the Armor Chest just has a Merc Adventurer Outfit in it.

I have no idea, but can tell you that attacking the Tribal Village by fast traveling to it is a bad idea. It drops you right into the battle between the Tribals and the Cazadores.
