Just a thought or Idea or Whatever Guys,
For the bottom drain on Mine,
I removed the factory drain and replaced it with the pull cord spit valve found on the bottom of the air tanks of a truck/tractor.
Like My Mack at work,just reach by the space between the Bat. Box & fuel tank and pull the ring.
It has an approx 36" clear plastic covered braided cable for a lanyard attached to make it remote!
regards,
steve sr.

p.s. made it remote to the outside with a pipe and hose.
