my first military vehicle was a dodge M890-19 years later i still have it,it still runs,and i wont let it go-i,ve had it out in mud,but nothing serious-i t always got me there,i,d say go for it-offer scrap money,they can only say no.
the amount of work to convert it to a 4wd would not in my opinion be worth while as the 2wd has IFS.
get the m890 ,run it about learn your way round it-as you start driving it you,ll be suprised what turns up! my dodge has bought strangers up on the street who had military vehicles rotting away,and would be i be interested?
good luck with your dodge-they are great trucks-there really is something about them!!
