If your real goal is to "Have a Blast" then by all means rent a Dozer. But if you want to get something done, you should hire an operator with their own machinery. For myself, there was no difference in cost, since it took so much extra rental time, learning how to use the machine and cleaning up the mistakes I made. It was a very fun experience. But further work, I left to the pro's.
Another problem possibly to overcome, we are gonna drag the containers to the pad and thru the pad, the pad is level and packed pretty good but sand nonetheless. Im sure that all that is gonna go away fast once we start dragging the containers thru.After you get the containers located where you want them, and level, weld some clip angles at the top, middle and bottom of the inside corners.
