OK - thanks - appreciate your input, NC!
It does seem a lot of them have a coolant leak!
If I bought one, it would be for local use only so maybe the original engine would be fine, given the coolant system is working properly.
Also the smog check thing wouldn't be an issue here in Florida - we're exempt.
There's something about these units that I like. I know I can't afford a Unimog - or a double/single cab - might as well get one of these!
