Thanks for the info everyone.
The green army type are just what I was looking for, but obviously not in the right places.
I also carried 3 yellow plastic jerry cans over many K's without problems, but they are my Diesel containers. I think that yellow is the recognised colour for Diesel and red for petrol. Everywhere I tried it was a choice of Red Yellow or Clear/blue. No Green HD.
It was the clear/tinted blue containers, nominated as for water that I had splitting problems with.
I had not come across the green Army type before and thats what's great about this forum, been able to tap into other's experience and ideas.
Thanks
