Weight of jerry cans

RD = 0.78. Close enough.

Ray, how flammable is diesel? Could it be ignited by sparks, or would it take a flame to ignite it? (or mixing it with fertiliser)

Depends if you filled up with "funny diesel" or not !

Don't forget that it's against the law to mount fuel jerrys' on the rear of the vehicle. If you noticed recently, 4x4 monthly did a little 1/2 pager about it.

The classic example is Kaymar's rear jerry holders... Now they have the words "NOT for carrying fuel" or words to that effect stamped into them...

It's really hard for an non-registered non dangerous-goods vehicle to carry fuel.......

I personally think Kaymar jerry holders are a waist of time/money. If you have an already large fuel capacity what's the measly little 20L going to get you? You're better using the space for a much more needed second wheel carrier.
Sorry Nordave, a bit off the track there.
