I'm running a Little Larrys valve block. I chose it over the DLOE route simply due to sanitary installation and the fact they are quick and easy to rebuild with generic o rings if ever needed.
The sanitary part comes in where you just have one inlet feed from your tanks to all four valves. And the combined single exhaust port is nice too since it was easy for me to run my dump line down and under the truck for quietness and cleanliness.
