We did not weigh 27-EX chassis before it went to the coachbuilders. We can say, however, that it will be approximately the same weight as a standard chassis. We consider the addition of the shock absorbers will about compensate for the weight we have saved in the road springs. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
