Offroad-Express

I'm buying a Mu for a work vehicle rather than a recreational 4wd.

What little mu specific problems should I be on the lookout for? Due to location I probably won't be able to check it myself before buying so I'll be relying on either the AA or my bro-in-law who happens to be a diesel mechanic.

Cheers.

watch the turbo isnt whiny mine was when i got it lasted about 3 months and blew the turbo. real common problem with them non reconditionable turbos. otherwise only broken stuff offroad
