After looking around some of the custom-made fire trucks I decided to have at it with mine. Unfortunately I am not yet as experienced so I decided to simply Update and remake the one's available in current LEGOŽ construction sets.
The First up was the 7239 Fire Truck. I tried to stay realistic and remake it into an equipment truck. I kept the cab and added internal equipment storage and a light kit at the top. It can still carry a ladder but it is not the mechanized one. I have no 2+ store buildings in my collection (actually right now I have NO buildings) so I did not need the Aerial Ladder.
EDIT: In response to SM: Thanks for the rate! I used a lot of pieces from the set but they were not enough to finish it so I added some. Many pieces that I added from my own collection did come from other Fire/City LEGOŽ construction sets. You may notice quite a few if you look hard. They are all from the newer 05-07 sets.
We'll let George show us around. Notice I kept the front cab intact. I have seen a similar truck made by someone else that has inspired my to remake this into his (forgot who, sorry) but that will come later.
