What is the International LT?
International lists LT in its heavy-duty highway range. It is one of the truck families offered with the S13 Integrated Powertrain, although the LT name also covers vehicles with other earlier powertrain configurations. Model year and the actual engine specification are essential parts of identification.
What matters in a comparison
Compare an LT on the routes, loads and cab requirements that matter to the operation. If a seller cites S13 figures, confirm the truck actually has that system and identify the model year. Keep financing or depreciation, maintenance allowance and fuel assumptions separate. A newer powertrain claim is not evidence of lower total cost for every used-truck purchase.
Questions to take to the supplier
- Which engine and transmission are fitted?
- What cab and sleeper setup is included?
- Are quoted fuel figures applicable to that generation?
