Why This Truck Is a Target
- The factory cap on a Chevrolet LCF is fully exposed — no lock, no cover.
- A cab over build parks outside overnight where siphoning happens.
- One siphoning event costs $500 to $1,000 in fuel plus lost work hours.
- Contamination — sugar, water, dirt — can destroy an entire fuel system.
