Greasel.com sells a unit called the nomad. It appears one can just pull up to the old grease pit and pump wvo into the tank and drive off. The system seems to be fairly complete. I was curious if any of you have seen or heard about this system, any good points or bad points and if it is a good system does anyone make something comparable. At least with this, one doesn't have to gather the wvo and filter it at home before using it.
