While it is "get Robert time".
Have you fueled up your carrier from a Jerry can, "without a funnel etc", yet Robert? (no pourer allowed sorry) (you technically ruled it out with the "etc")
You second to last line refers to "carrying two Jerry cans by one man, no problem". You must mean empty ones!?
I was on exercise in Fiji in the early 70's. Every one was carrying gear. I was tasked with carrying a modern standard plastic 20 litre water container (full of drinking water) up a big hill. A long climb. I was wearing my webbing and a pack full of gear, along with the SLR (L1A1) and I will never forget having to carry that bloody thing.
Remember "gas" (petrol) has a S.G. of 0.76 or there abouts. Water is 1.00!
Don't give me "no problem!"
