Decreased repair costs

Here we use results achieved with Saccani Distributing as a case study to document the overall and financial effects of LDT Optimization on a vocational fleet. The following chart shows parts and service costs for the Saccani fleet during the 4 years preceding LDT Optimization service — and then for the 7 months following LDT service.

Before: $7,159

Average monthly cost over previous four years

After: $3,209

Average monthly cost after LDT Optimization

On average, LDT Optimization is saving Sacanni Distributing 55.2% a month on repair costs. Across their 25-unit fleet, this represents a savings of $158 per truck, per month — or $1,896 per year.
