I recently had my 2018 International’s DPF filter serviced by Gilbert Trucking, and I couldn’t be more impressed with the level of professionalism, attention to detail, and customer care I received. Gilbert and his team not only replaced the DPF filter with precision, but they also corrected misaligned DPF wiring that had been positioned too close to the driveline. They realigned it properly and secured it where it was supposed to be a critical detail that many others would have missed. The craftsmanship was top-tier, and the service was both respectful and efficient. What stood out most was how I was treated, the not just as a paying customer, but like a friend. Gilbert is a genuinely kind, knowledgeable man who clearly takes great pride in his work. He even went out of his way to help me get back on the road as quickly as possible. Many praises to Gilbert and his team. I highly recommend Gilbert Trucking to anyone in need of expert diesel service done right!!
