Horizontal Black Tank Vent

Hello,

Has anyone had to install a black tank vent horizontally? I am building a shower trailer and the way I have my black tank situated, I need to run the vent up a few inches then horizontally for maybe 2 feet before the vertical extension through the roof. I have build videos on Youtube (watch?v=zEOzA8TtWZ4) and I will post a video of this issue shortly. Just wondering if anyone has experience with this.

My plan is to install a tank level sensor right below the air vent so that the fluid level never reaches the air intake.
