Campbell Supply Company

Campbell Supply Company operates as a commercial truck and emergency vehicle dealership serving Monroe Township and the broader New Jersey region from multiple locations including South Brunswick, Newark, and Sussex County. With a 4.0-star rating drawn from 660 customer reviews, the dealership offers new and pre-owned commercial trucks alongside specialized emergency vehicles. The South Brunswick location functions as one of seven facilities across New Jersey and Orange County, New York, providing sales, parts, and service operations for fleet operators, municipalities, and individual buyers seeking commercial-grade trucks.

The dealership distinguishes itself through authorized partnerships with major truck manufacturers including Freightliner, Isuzu, and Western Star, along with emergency vehicle specialists Spartan and KME. Customers can access a full spectrum of services spanning new inventory purchases, SelectTrucks pre-owned selection, parts ordering, and mobile repair capabilities. The parts department receives consistent praise for technical knowledge that reviewers compare to speaking directly with diesel mechanics, while the service team handles everything from routine maintenance to complex warranty repairs.

Customer reviews highlight specific technicians who deliver exceptional service. A reviewer described technician Clarence arriving at their home during Christmas week to diagnose and repair an antifreeze leak on a new RV Freightliner chassis, going beyond the original issue to address a softwire recall and tighten components that should have been completed by the selling dealer. Another reviewer credited the parts department team with in-depth troubleshooting patience across multiple truck brands including Peterbilt, Volvo, and International, noting the staff takes time to understand issues rather than rushing through transactions.
