Hmmmmm....seems that I have to disagree with you again....the
vubration may get less cos the amplitude vs frequency curves tapers
off with a negative dy/dx, but in my opinion, due to all the
screeching and knocking and heat, it seems to go the other way,
i.e.dy/dx is positive, empirically. However, the heat vs speed
curve is definitely concave upwards.....ie the rate of heat
increase increases with the speed. As the A/C control is fixed, the
transmission to the A/C belt should be constant, hence it does not
get colder, rather, due to the engine heat from the rear, the
interior temp remains const at the front, but rises towards the
rear, that's why drivers dun know the bus at the rear is so damn
hot.
I agree with you, Scanias make a better choice for long haul than
MK IIIs, but i prefer svc 39 Mk IIIs to LAnce 211s any time
