Alternate 20 of set 5867. What would 8292 look like if you only have set 5867 to work with.
The colours that come in the set are excellent for making some kind of fire and rescue truck. However the problem is that there is a lot of surface to cover, which made me very doubtful if I could pull it off with the limited elements available.I went for some bucket truck, also called a cherry picker which I thought should give me the best chances. Besides it would add some interesting functionality. Still it was a big challenge to use every part efficiently. Almost none were left in the end.
