I may have told some of you about this, maybe not, it goes into maximising the space that you have under the bonnet and keeps in with the classic camper look, anyway here goes:
A few years ago at LATP I was admiring the SAS Land Rover and I noticed that under the bonnet there was some oil can holders, thinking it was a good idea fitting 2 x 1 Gallon oil cans under the bonnet making use of what otherwise would be dead space.
The inspiration
The more aware of you will notice that the overflow bottle is relocated, if you have a standard fan it will not be a problem.
The execution
Borrow a wing
Fold up some metal
Metal glue metal together, and test fit cans.

And fitted
All in all I personally think a good period looking modification!
