Mitch.
Our member 'Dodger' in the Southern Highlands is into these, so if you click on 'members' [top left panel] you should be able to track him down.
He just might be interested in it.
You say that you are in Goulburn, & that you shower twice a day.
Remembering that Goulburn has been on level five water restrictions for the last several years during their worst drought in recorded history, & remembering that Pejar Dam [the main storage dam] was officially declared dry a while back, it might be an idea to keep that info to yourself as that kind of outlandish water wasteage might cause you some problems in some quarters.
Your 521 is a dropside, flatbed truck & is the contemporary commercial vehicle equivalant of the Datsun 1600. [P510]
