uhhhhhhhhh, irishtom, surely you are aware that you are preaching to the choir? :W
It was interesting to note that it did not take the OP too long to notice that the diesel drivers all carry on bout how that is the only way to go and like wise the gasser guys do pretty much the same. But it is my opinion that the diesel drivers constantly lurk for a chance to bash a gasser. :B Nothing else to say they have to lean on the "S" word (screamer).
I am convinced that the gas motors have come into being and are continuing to advance, surely because of demand.
