Can you show me your bedbox platforms..

It seem practical (for my purposes), to put a platform on the bed and have storage underneath for several reasons.

You can store out of sight and lock it.

I keeps a lot of small stuff under and if you camp, you can sleep on top of the platform w/o clutter. So it makes two shelfs instead of one large shelf. The surface area is doubled.

How did you affix it to the bed or is it in place there by gravity?

 

This is not mine, but it seems to be exactly what you are looking for.

Picture one

Picture two

It is rogersja63's truck, Perhaps you can shoot him a PM for more info.

 

rogersja63 had such a badass truck! I havent seen him on TW in a long time though...
