I have been actively reading the forums since release and have yet to see a compiled list of vendors in game.

I am currently on my third play through with 140+ hours invested into the game and I have yet to find the vendor located at hoover dam. I have read posts regarding this vendor but still can't find him. I'm sure others feel the same way about this vendor or other vendors they have not located.

If anyone out there has a master list, please link it so we can find the ones we are missing. If their is no master list, lets create one.

Goodsprings - Chet - General store
Primm - Nash - Vick and Vance casino then moves to mojave express
Novac - Dino Gift shop
T188 - multiple vendors
Airport - Contreras past the concorse
Crimson Caravan - Blake
Gunrunners - Robot
NellisAFB - Hangar that contains the mess hall
Freeside - Mick/Ralphs & Van Graffs
Hidden Valley - Knight Torres - Shooting range

I know those vendors consistently restock every 72 hours and if I'm not mistake have a chance of having weapon mods.
