Oh that is weird. When I looked at the Technic site at www.lego.com/technic,
it showed that both side doors could be opened at the same time, or was it an
error? Oh so that is the purpose of the 1st knob. I thought the 1st knob
controlled the front steering and the back knob controlled the rear steering.
Well that clears some stuff. I know what you mean by the space limitations.
Inside the truck, without the engine and cab, the middle section is divided into
three because of the axle that connects the knob with the chassis of the truck.
The easiest place to put a tank would be right in the middle sicne that is also
the place where the side doors open.

I don't want to make this project too complicated since I am new at Technic
(I only have the 4x4 Off-Roader and recently bought the Extreme Off-Roader). I
was thinking of other projects like how to turn the Extreme Off-Roader into an
RC Truck using the base from the RC Race Buggy and to place an air tank instead
of the engine for the back-hoe but this project can't be done since the
pneumatic pack from Shop@Home is not available anymore.
Since I can't get an air tank, I was thinking of buying a pneumatic pump and
pneumatic tubes and maybe I can find a very small container, make a hole,
connect the pump and the container using tubes and modify the cannon using more
tubes from the container to outside and replace the original. And of course I
will fill the tank with water and see if the pump puts pressure on the water and
pushes it through the hose on top. Problems are right now that I need to buy the
model and see exactly how much space there is and how could I stop the water
from coming out?
