New 2020 Vegas 27.7. looked underneath and there is a black gate
valve (looks closed) on the passenger side in the 3" pipe going across the bottom What is it for? The gray and black dump valves are on the drivers side.
Thanks
Just for added measure of protection, I installed the Valterra Twist On Valve. I'm a little concerned that it sticks out from the coach body as it does, however it does not stick out as for as the chassis exhaust or the generator exhaust so it should be ok.
