1973 Power wagon W100 question
 

Hello everyone, I'm new to the site, I have a question about my 73 power wagon W100 Reg cab short bed, I just got today. I was going over it and noticed something I have never seen on a car or truck before, under the carpet on the passenger side was a trap door with a metal box under the floor boards, it is about the size of a shoe box. Also under the bed cab area is a similar box but it is like 2 feet long about 6 inches wide-the bottom and sides are rusted out. What are these boxes for? Beginning to wonder if I have some kind of smugglers truck, might grandpa and uncles use to have cubby holes in their cars in the hills for running moonshine back before I was born. I might reform these cubbys with new steel and make them into tool boxes. Thanks.

Sounds like there's definitely a story there. :D
