I got it locally from a guy that bought it in Ohio last spring. He bought it without enough work and then had to sell it because he was moving out of state. He never even had it inspected. It just sat all summer.
I got pretty lucky as it is a very clean truck and only needs to have the plumbing redone.
It took me 6 months of looking for a used plant health care truck before I came across this one.
Good luck with you search. Finding one complete and in working order seems to be rare.
