One word I'll mention 3 times.....CHASSIS, CHASSIS, CHASSIS.
If the chassis is solid everything else is just nuts and bolts and leads me to say.....it's a deal it's a steal, it's the sale of the f**ing century!
Edit....yes I'd say its ex utility company, probably electric company.
its got a winch bumper which has been removed.
Also difficult to tell from your pics but it doesn't seem to have the rot in he usual places which is also a bonus.
