Started with trying to strengthen the paper folded metal like bed caps that are under the plastic trim and just got more reinforced and organized as the truck got built out and i realized the whole bed structure is one step above cardboard. This is version two- if it goes to 3.0 i would just lose some of the angular stuff. Holds a 315 with room to go up at least 37", 5 g water, 10 g gas, a useful sized extinguisher, bottle jack, shovel, air hose,and my 2 nd battery control charger and fuse box. It can still take a typical palette- but even if i have an old cast iron tranny or a motor decides that decides to wander lose it won't hurt the cage or wipe out the bed. Only downside is it makes hauling loose material like soil or rock a bit of a pain- but it's only a 5'7" bed before it lost about 14" so i just have that stuff delivered since 3/4 a yard at a time is a dumb use of time. I also just cobbled up the kids old pitch back frame into a cap frame i'm going to see how the slumber jack road house tarp works with. Like i said- for the cost of some of the better accessories out their you can get tools that will allow you to develop some skills that will only become more valuable as the world gets so smart people can't fix toilets.
