Ever get an on-site pump out of your gray/black tanks?

So he said he is driving around every day pumping out trailers on site. What a job! :)

Actually the CG route may be the nicest type of work available for those pump trucks. Around here they're typically servicing portable outhouses and pit-toilets at trail heads. I'm sure Mike Rowe did at least one Dirty Jobs episode like this.

Doing all closed-circuit work is probably nice (other than the bending/crouching), and your customers are typically going to be a very happy crowd.
