Ok. So since I only going for 2 in the crane (maybe 3 for strength) and one
on the tipper (or maybe two for length here), I realy dont need the tank?
Anyone that have a SMALL and COMPACT solution to controlling the valves
through the RCX? There should have been magnetical pnaumatic valves avaiable
from Lego, maybe I build a realy small one myself?
That would be a nice thing Lego could have made next :)

I realy want to use the 8461/8458 Wheels, but I only got 4 of them :(
I'm searching the town for a Silver Champion set right know. Those wheel
will give the truck a "street look" but right now I'm using the 8466 wheels
(have eight of them), this give the truck a "offroad look", so it would
probably be more lika a TARA truck.

As you probably can see on my Brichshelf page, I've toyed around a lot with
the suspension.
And even when I was pretty satisfied with the design I have changed it. And
would probably make another change when I go furthere into making a stiff
chassis.

The Williams F1 uses the same parts all over, included the dampers, only
diffrent colors. The only parts that differs are the panel firings, they are
smother on the Williams F1.
And they have rebuilt the front and rear wing. Otherwise it is indentical.
But I would like to have the Silver Champion only for the color on the
parts. I like black. :)
The absorbers are stiffer as you say, but in my construction they was TOO
stiff. So I changed back to the standard 6.5L dampers (part # 732 /731). The
chassis is pretty light right now.

I hope you will play with it your entire life, but it looks like almost
everyone here that is a bit old (like myself) have a rather dark period of
Lego building time in their lifes. My was the time from when I went to the
navy and spent 3 years on a submarine. But after I got my own apartment I
started to play with Lego again.

Russian truck company I think.
I know I've resently visited their site, but I've forgotten to save the URL
:(
But I will send it when I find it again.

Well, I've tried to put a chassis on it now. And you can look at it at
brickshelf:
