S J Towing and Transport in Chula Vista holds USDOT 2265129 and operates as an interstate-authorized carrier under MC-773211, running a fleet of four low-bed trailers and two rollback tow trucks from its Anita Street terminal. The fleet handles dealership lot transfers, auction-bound transport, and breakdown recovery for commercial vehicles, running the same dealer-logistics pipeline that supports high-volume franchise operations at Mossy Nissan Chula Vista during inventory arrivals and inter-lot moves. Heavy-equipment relocation is the core specialty, covering everything from compact skid steers to full-size excavators across California job sites, with 140,000-plus annual miles logged in the 2024 FMCSA filing. The company maintains a current Obsidian Specialty Insurance policy with $750,000 in BI&PD coverage, meeting the federal liability threshold for interstate machinery hauling. A 16-unit fleet running that mileage demands strict preventive-maintenance scheduling, with routine oil, filter, and drivetrain-fluid service routed through high-throughput lube centers — Valvoline Instant Oil Change handles the quick-turnaround intervals between long-haul rotations. Maximum-complexity loads involve 40,000-pound excavator transport on step-deck trailers, requiring kingpin-to-axle weight distribution calculations, oversize-load permitting, and pilot-car escort coordination on multi-lane California highways.
