I got a few questions:

• I found a second hand truck on the internet saying that it has a wheelbase of 4400mm. Am I right that the wheelbase meens the distance between the steering axle and the centre of the boogie?
  It works out to be something like 330mm. I added the length of my sleeper to it but it just looks like it is still too long.

• Currently I´m working on the fuel tanks.
  I found a 40mm pipe that is just as big as the Tamiya fuel tank is. The problem is that there is a pretty huge gap between the tank and the frame. Is the tamiya frame just not wide enough or is the tank to small?
  I imported some pictures into my cad software and it confirmed the 40mm
  No one would probably ever notice but I know that it is not 100% correct
  Has anyone got photos of the brackets?
