Black tank Drain Valve location

[Bon Voyage]

Hey I'm getting ready to install the 3" black tank drain valve and looking for input; hopefully from experience...
The black tank outlet is in the middle of the bus so I have to run a line from the tank to the drivers side so I can hook up the drain hose. My question is do I need to put the gate valve right under the tank or can I put the valve closer to the side for easier access to pull? My concern is if I put it at the edge where it's more convenient - the 3" pipe (which will be a few feet long between the tank outlet and the valve) will fill with solids and it won't want to come out when I open the drain.

Anyone done this and gone problem free??

I have had rigs set up both ways.

My trailer has the valves right at the tank. They extended the handles about 3' to the edge of the trailer for easy reach. It works well.

So you didn’t have any clogging problems when the valve was a few feet down stream from the tank?

Only once........ I don't want to talk about it. I'm still in therapy because of it.

Seriously, the only reason that I have not installed a composting toilet in the trailer is because I have it up for sale.

I have found the valves directly at the tank is preferable until you have to work on them.

EST ain't got nothing on a fecal lavage.
Or so I hope never to corroborate...
