1999 Ford f800. My friend was in a pinch and really had to get the truck off of site and I had space for it. So he just gave it to me, I don't know much about diesels. It hasn't been registered since 2012. I did put two new batteries in it fired it up and drove it around the block. it didnt run well it needs a tune up or something. Has Cummins motor and Allison automatic transmission. A 24-ft box and a lift gate
