One of the challenges when building a custom classic truck is finding a spot to put all the components necessary to make it operational in what is often a small space. It's the old 10-pounds of stuff in a 5-pound sack scenario.
Recently, our fearless editor, Ryan Manson, was confronted with that very issue; there was a battery to be mounted and no good place to put it. A somewhat hidden location, like under the bed, would be ideal but a battery is something you should be able to get to easily. The solution to the problem was found in the pages of the Speedway Motors catalog in the form of a dropout battery box.
Just what was needed, the Speedway box would allow the battery to be mounted out of the way while still being able to maintain access. The box normally locks in the up position or it also drops down and locks 41/4-inches lower if needed. It will also drop the box completely out of its mounting when maintenance is required.
To mount the box, a simple angle iron structure was fabricated and welded to the framerails. The battery is now hidden under the bed, but is easily serviced-don't you just love it when a plan comes together?

The best spot to hide the battery was to hang it off the framerails under the bed; the obvious problem then becomes access.
