there were a lot more AD's made, 8 years as opposed to 4& 1/2 for the TF series .... but there are just as many AD 'models' as TF, small to large, panels, burbs, COE's etc .... if most folks shared your opinion, you might have never been able to find a "real55"
all a matter of personal choice, and influenced by ones age and intentions when acquiring a truck - the TF isn't really mechanically much different, but a lot more of the "wearing" parts are still in the retail system, so maintaining things like brakes can be easier - and of course it's easier to have a V8 in a TF, but the 235 is about the same as earlier and can be a good reliable engine
