Short answer: no. There is no free, public, VIN-in-value-out tool for semi trucks the way Kelley Blue Book works for a used Camry. Every real valuation guide for Class 8 trucks is a paid professional subscription built for dealers, lenders, and insurers, not a walk-up consumer tool. Here is exactly what exists instead, and what to actually do about it.
The real guides, and why none of them are free
- J.D. Power Commercial Truck Guide (this is the old NADA/ATD Official Commercial Truck Guide; NADA sold its used-vehicle guide business to J.D. Power in 2015). A subscription runs $840 per year. The old free consumer site, nadaguides.com, now redirects to a dead link. This is the closest thing to an "official" number, and it is not free.
- Price Digests / "The Truck Blue Book" -- yes, there is literally a product with "Blue Book" in the name for trucks. Online access runs $599.95 to $1,399.95 per year depending on the tier, with one-off single-vehicle lookups also sold.
- Black Book Medium & Heavy Duty Truck Values -- $362.98 per year, marketed to dealers and lenders, no free tier.
- Iron Solutions / IronGuides and Rouse Sales appraisals -- the tools banks and professional appraisers actually use. Login-gated, quote-based, not public.
Every one of these targets the same buyer: a dealership, a lender, or an insurance company that needs a defensible number for financing or a claim. None of them are built for a person buying one truck.
What RigDig actually is (it is not a valuation tool)
RigDig comes up constantly in this search, and it gets misunderstood. RigDig is a history report, the Carfax-equivalent for trucks, not a price guide. Its own product page lists exactly what it checks: junk or salvage titles, recorded inspection violations, carrier safety-maintenance alerts, total loss insurance claims, out-of-service violations, cargo types hauled, DMV title or odometer brands, prior carriers and owners, recorded accidents, and UCC liens. There is no price or valuation estimate anywhere on it. Useful for verifying a truck's history, useless for telling you what to pay.
What an actual buyer can use for free
Since there is no single lookup tool, here is the real process:
- Pull 10-20 live comps from TruckPaper and Commercial Truck Trader for the same make, model, engine, and mileage band you are considering. Free to browse.
- Check completed auction results on Ritchie Bros. or IronPlanet. These are actual sale prices, not asking prices, which makes them more honest than a listing.
- Run a history report (RigDig or similar) on the specific VIN before you commit money, separately from pricing it.
- If you know a dealer, lender, or fleet manager, ask if they will pull one number from J.D. Power or Price Digests for you. Some of these guides sell single-vehicle searches a la carte for well under the annual subscription price if you have an account rep to ask.
Why this matters more than it sounds
Without a KBB-style anchor number, every used-truck price is a negotiation starting from comps, not from an agreed baseline. That is exactly why the model-level, sourced records on this site exist: real observed listing ranges, tied to a date, instead of a single number nobody can verify. Check our truck records for documented market ranges on specific makes and models where we have gathered enough real listings to publish one honestly.
