I put a bit of thought into that sort of thing DK before building Dobbin
I settled on the vaulting horse shape as it could fit into itself and go in the back of my car and then the bocks and gear gould go into it to save space and I could still use the back seats (handy size the Disco) and I've made another bit to go on the lower two sections so making two smaller platforms
So measure the size of your Boot/Hatchback thats the biggest and make each one smaller to fit into the last one because unless you are leaving them on site all the time you will have to transport them
And don't forget they have to be heavy enough to stay put when you hit them and strong enough to take constant pounding from some heavy bocking (I put extra supports under the platforms on Dobbin)
Feel free to copy Dobbin (or any part of him) DK the pics are self explanitory
Another idea I had was to use a small to medium trailer to transport the boxes and use the trailer itself a a large platform
Or even a roof rack with a flat sheet on it to act as a high platform when you park the car (bit too high on the Disco
![:haha:](http://www.projumpforum.co.uk/Smileys/default/haha.gif)
) but most cars are low enough to jump from once you get good (could even extend it to the bonnet with a few brackets and windscreen protection)
I'm working on a folding extention to Dobbin at the moment to get some extra height (for people like tundraH who are just to good at high things
![:biggrin:](http://www.projumpforum.co.uk/Smileys/default/biggrin.gif)
) and to use him as two high platforms
