If you are going to open up a discussion then you need to learn how to communicate with people, you can't talk to people dismissively on or off the internet and expect them to entertain your notions or even want to talk to you, it's basic social skills that most people should know. I wasn't going to respond after my last post because you seem to have this tunnel vision with your own ideas but to name a few spots that fall into the same scenario:
-seen 1 PERSON hold off the whole server on Little Italy in the basement when they use the fridge as a barricade in the corner
-also 1 person holding off the whole server when they use the vending machine on the sloped staircase on Little Italy just above the basement
-2 people hold off a server of zombies on rush_final at the concrete pipes many times just by alternating their reloads well
-seen a few people hold off everyone on rush_final at the high platform through the teleporter
-seen a few people hold off all the zombies on the box glued to the wall on rush_final (the one people try to run boost to)
-seen 2-3 people holding off server of zombies in a couple of spots on Westwood (the kitchen room and the fridge barricade at the saloon)
-oh, crazytown, the sewers are massively OP when barricaded well, only takes a few people to hold it off but with a group it's extremely difficult to take over
-the small room in crazytown with the glass barrier can easily be held off against tons of zombies with just 3 or 4 players
-another spot in crazytown, using a single vending machine to block yourself under the crates in the garage area (1 person can hold that)
And i have seen the truck get taken down lots of times, by one person and by congested zombies just pushing their way in. If you want to just gloss over every response then there isn't much point in me replying.
