Thanks for the comments...it was a lucky find. I've got my old man to thank for that.
Bruce- like Joe said, it's an electric brake controller. I'm thinking maybe it's a manual deal by pulling the lever down to engage the brakes, but I've never seen one that old before.
Brad- I didn't know what those road flares were at first, but I gigured it out. They are pretty neat...they still have kerosene in them.
Jock- Already had the security system. He'll gladly look after the truck along with the house though. Once he jumped in that truck he didn't want to get out!
