Commercial Truck Inspection Appraisals


Financing or insuring a Commercial Truck is taking a large risk.  We help reduce that risk by verifying the vehicle’s condition and value for you.   We perform our detailed inspection of the vehicle AND provide a current market certified appraisal as well as photo document the vehicle’s current condition so you can make an informed business decision.   Don’t need an appraisal?  You can also order the inspection by itself as an asset verification inspection.

We fully inspect the body, interior, features, options, electrical and lights, engine, DPF, transmission, clutch, driveline, suspension, steering, fuel & hydraulic tanks, brakes, air bags, wheels, tires, 5th wheel, cargo area, doors and all glass to ensure you know the true condition of the vehicle.

When I go out to inspect a for my clients, they know they are getting a true independent and unbiased inspection report.”
