Well just like the title says, I find that there is almost no crafting support in the way of ammo crafting and food crafting.
Although it does apply a level of challenge, since many of us will play hardcore, I often find food is an issue. But ammo, pretty much any vendor that has guns should offer more in the way of do it yourself ammo than raw pure ready for use ammo. Also I've only seen 1 surplus box on Moira Brown, kinda disappointing.
I do appreciate that I can cook Mire lock meat.
Edit
So far I've found 5 entry's for Venderammocrafting I tested out 1 of the entries putting a count of 2, I think that you need several separate entry's to achieve a better since of variety. I have not found the entry for surplus ammo which I think Moira should have quite a bit of.
Moira Brown, Lucky Harith, and Flak n Shrapnel should have ammo crafting supplies, surplus ammo, and weapon mods.
Several food vendors and Doc Hoff should have selections of Food items from FNV, I know doesn't make since in a regional RP standpoint, but without a crafting list for DC offering lots of food and home made chems, it just seems to me it would be easier to explain that they receive these goods because of trade.
Doc Hoff and a Quick Fix should have a wide array and quite a bit of the chems from FNV.
Leo Stall should have a Low to Mid level list for chems
Moira Brown should rarely have Super Stim Packs
I'm about to start tweaking an ESP now and if you have some idea's to offer feel free to do so, I may upload it when it is finished. I'm sure many out there would like to see this a bit more fleshed out as it were.
Update
I can't seem to find an inventory list or container For the caravans (well I found the list but it has a script for them ie Lucky Harith, Doc Hoth, Wolf Gang, and Crow). Aince these are caravans it'd make since that they could have exotic goods). Perhaps someone with scripting skills could make a list reflecting expansion of their goods via the quest that is available for them in game.
I have had some nice well easy success altering Moira and Flak n Sharpnell lists, So far I'm trying to balance the amount of ammo crafting supplies they have, I assembled a list that uses the ammo teirs 1-5 and then smacked that on their containers...Thing is it's too random they get a lot of supply in the mid range for ammo...I'd rather see a lot of 5.56, 9mm, and .357 over other types...I'll probably have to hand place those types for crafting.
I've also noticed something else about DC...Bottles of water are actually rare, when playing "Hardcore" you tend to consume a lot of water actually. So much in fact that I often drink from the various water sources rather then use bottles of water. It seems too me that food vender's should have bottles of dirty water to sell and some really rare pure water. Now for some of you playin this may not seem like a problem but I altered my Megaton Home Mod I'm using to have the absolute worse water for all of it's sinks and toilets (water lvl 5, with PN it's 18 rads a second). Although their are Perks to bottle water in Dree's More Perks it does not seem to be a proper solution.
