sorry I replied to the wrong thread. Stressed and tired.
It's a stolen and recovered vehicle and the listing says that the catalytic converter is missing which is a huge deal in California, but in the UK it isn't. You can also see from the photos that both battery trays are slung in the back with no batteries.
There might well be absolutely nothing wrong with the engine, or it might be knackered. You can get a good used 6.0 from a place in Ohio for $2500
However after a couple of hours soul searching I have decided that I am out.
My dream is dead for now.
Auction is in two hours.
Here is to the vehicle:-

You can't bid on that site without a trader license, but if you want to buy it you can bid here:-
https://www.salvagebid.com/search?search_query=29333386
you have to give them a $400 returnable deposit to actually bid and $200 for one year to live bid.
If I lived near to California I would be all over this, but I don't.
I need to get some perspective. Family are all healthy, we have a secure income and a nice house. It's just a van.
