I have not heard of that brand, does it look like one of those chinese knock-offs?
There are several guys driving around town with a generator that is gas, one is diesel, a pressure washer, and some other equipment that looks good but are the knock-offs.
They are selling them at good prices but nobody around here will service them or do any warranty work on them.
Find out if there is a place that sells them or will work on them first.
It sounds like a good deal.
What brand is the diesel engine?
