No quests, no looting, no stashes, just run to the exit and camp.
First off, extract camping is a total crapshoot in terms of what you'll get. You could kill a grub and make 30k, or you could get the drop on a gigachad and get 400k in one raid from another man's loot.
Overall once I got used to extract camping I rarely ended up dieing from it, although sometimes my exit would get rushed by a full group and I wouldnt be able to do anything.
The best map to camp is reserve (D2) and, surprisingly, woods (outskirts).
Reserve is obvious, the path to the exit is long and there's tons of opportunity to hide + it's all close quarters.
What I found with woods is interesting. Every exit camp you either got a vepr hunter/Mosin guy with no armor, or a guy with a cannon capable of smiting God and 40 fucking kilograms of barter items.
Outskirts is a lot harder to exit camp since people just sit behind the car when they get close, so I camp prone in a bush very close to the car with a shitty little mp5 and pst gzh since nobody brings good armor to woods since "The armor will get pen'd anyway" so they only bring paca and penis helmet even if they bring a thermal.
The best guns for exit camping would have been shotguns for sure, but because of the glitch where your game would lag if you used one I couldn't use them. Instead I would bring a 5.45 AK since it pens pretty well and I'm close enough that the recoil doesn't matter.
I have almost no quests done, I'm probably poorer then someone who quested the game, but on the bright side I got to farm runescape for 45 minutes every raid and still whooped your ass!
Also, before you go into an insane ramble tangent in the comments psycho analyzing my words and post history trying to find a reason to tell me to 'get help' or some petty soy bullshit, grow a pair. This is tarkov, and I'm not gonna let you escape.
