Neil I have no idea what they would sell for this one was bought at an auction where no one had any idea what the potential of one could be I think I got it for a hundred bucks, but would have gladly paid 3 times that.
The floor is 1 piece smoot 1/4" thick aluminum. Sitting on the cross ties I figure it will be more than suitable for what I intend to do with it since the refinery system will weight about 800 lbs once I refurbish and up grade from what I got with the 600 gallons of oil. The guy had about the crudest set ups I have ever seen undersized centrifuge dodgy filtration and inadequate heating leaky pumps and a very labor intensive way of processing. He could only achieve a dark brown diesel like fuel and in no way was able to make bio diesel out of used vegetable oils since there was no provision for a blending step.
It might take me another year to put together a system I will be comfortable with to run the diesel in a later model pickup but what he had would run in an older farm tractor just fine or my 90's era pickups
