If you're covering stuff with a tarp, you don't need to expend your accessories; a blocky shape under the tarp will be sufficient. 

That's what I'll do. I'm trying to think of a way to make something that looks like a pallet of water bottles.

There's the Vietnam trucks like Iron Horse and Eve of Destruction.

Ken mate to build what ya want is dead easy ..you can build a wooden pallet from plastic and just stuff a block of whatever you want to use on top..cover it with a tarpaulin and your done .
I filled the rear end of a Kangaroo Sherman with what looked like a very large load of cargo ..all it was was balsa wood stacked up and glued....then I covered it was a tissue ..pva glue and let the weight skin into the gaps to give it a  heavy look ...worked a treat bud
