Incorporated in 2019, California Coast Truck Repair in Santee is a BBB A+-accredited NAPA Auto Care Center on North Woodside Avenue specializing in medium-duty and heavy-duty diesel truck repair, trailer service, and motorhome chassis maintenance. Tire and wheel service for Class 6–8 commercial trucks coordinates with Wayne Miller's Mobile Tire just 16 addresses south on the same Woodside Avenue industrial block. DOT safety inspections and California BIT compliance audits — performed under USDOT 3345820 registration — cover braking systems, ABS modules, lighting circuits, and coupling-device integrity for intrastate commercial carriers. Diesel diagnostics and full engine swaps, including documented Ford 6.7L Power Stroke replacements on F-650 platforms, serve the same commercial fleet operators who source vehicles through Budget Truck Rental on Mission Gorge Road. Leveling jack overhauls, onboard generator rebuilds, and chassis-mounted HVAC system repairs address the full mechanical scope of Class A and Class C motorhomes.
