Wow, that's some backpressure.... if you're not good with tools you're gonna have to take it to the dealer to get that fixed. Until then close the valve you got open and pull the others so you can empty the tank.
If you pull them one at a time you should be able to tell which is really the black tank cause the toilet ought to go back down.
Sounds to me that the dealer didn't check the valves during his PDI and it also sounds like the vent is too far into the tank, otherwise as mentioned you'd have seen a rain of poop running off the roof.
