Check it over really well if you go look at it in person. I know the service bed on my dodge would be difficult to remove. Not saying it's impossible but would be a heck of a job.
It's bolted in a lot of places and the bumper of the service bed is welded to the hitch which is bolted to the frame. The gooseneck hitch is welded to some crossmembers that would need to be cut out as well.
Clean looking K30 though! I'd slap some wheels/tires on, remove the rack and run it!
