We had a half full wine cask bladder rub through on the canning.
For water, we took 5x25 L good quality plastic drums. We drove over some of the worst corrugations I have seen. The plastic drums held up fine, and were convenient to use and refill.
The strongest and most durable container I have though is a 20L plastic drum that used to hold 7-up concentrate. It took weeks to lose the 7-up taste though and years to lose the smell!!!
