Going to look at a K30 with a slide in wrecker

[rs74]

I think it is an 85 dually with regular dually bed. Is there anything in particular I should look at since it has the slide in wrecker in it. I am thinking it is a Holmes 440 in the back of the bed. I have no use for the wrecker part but am interested in the truck it self. Just didn't know if due to it having the wrecker in it if there might be trouble areas to look for. It is a Scotsdale with 454 and an auto. Not sure on transfercase yet.

I will post pics tomorrow after I get back home. Not sure what he is asking yet. I will have to look into where a good place to get rid of the wrecker at to see if it would be feasible to go ahead and buy it.
