Name anything mechanical about this truck and both sheets answer identically. Name anything about how carefully a form was filled in and they separate. The whole “1,172 dollar question” turns out to live in that second category — almost entirely.

Twenty-three lines that match

Read straight across and these are not two products. They are one driveline, one frame and one box, entered twice — by one listing at $43,736 and by another at $42,564.

Twelve lines that do not

Half of them are absences rather than differences — the cheaper sheet simply does not fill the field. That distinction decides the whole comparison, and it is the part a buyer usually gets wrong.

One divergence survives the audit

Strip out the rows where one side is blank and one genuine difference remains: the gearbox casing. One sheet writes 12G200TD aluminum (Q) with soft-shaft control; the other writes 12JSD180 (Iron, Q-type) from FAST (Shaanxi Fast Gear). Same ratio count, same maker family, same Q-type suffix. What changes is what the housing is made of, and it changes inside a casing that neither sheet publishes a weight for.

Everything else that looks like a difference is a difference in how carefully a form was filled in. The $43,736 listing names its chassis kerb weight at 10460 kg; the cheaper listing leaves the field empty, which is not an assertion that its chassis weighs something else. It names a desert air filter, semi-floating cab suspension, automatic air conditioning, a source project and a base-model change note. Those are rows that exist. Absence is not specification.

What the 1,172 dollars are actually buying

The premium is 1,172 dollars, 2.8 per cent. Against a difference that consists of one unquantified component, that is a very small number — close enough that either of two explanations fits it: a genuine aluminium-casing specification, or a repeat listing entered later with a fuller form and slightly different pricing. Nothing in the published data separates those two, and pretending otherwise would be guessing.

The decision, stated plainly

Buy on the one question you can settle and nothing else. Ask both listings for a written gearbox model with casing material, then ask what a replacement casing costs landed at your port. If the aluminium unit on the $43,736 sheet is genuinely specified and genuinely cheaper to keep alive on your roads, 1,172 dollars is background noise against a 43,736 dollar purchase. If the two quotes come back describing the same gearbox, take the cheaper listing — and ask why the second one exists.
