How appraisals work
From VIN to value in four steps.
An appraisal is only as good as the information behind it. TrailerBook collects the right details first, then does the analysis.
- 1
Trailer
Enter the VIN, or snap the VIN label to fill most of it in. Confirm the make, year, size, GVWR and hitch.
- 2
Condition & equipment
Rate the overall condition and add factory options and any equipment added since.
- 3
Photos
Upload guided photos — VIN plate, frame, tires, deck, hitch — so condition is assessed from evidence.
- 4
Review
Check everything and submit. Specifications, photos and service history are weighed against the market to produce your appraisal.
Appraisals are an informed estimate, not a guarantee of sale price. Every report lists the details and evidence it was based on.
Maintenance & service history
Stay on top of maintenance. Prove it when you sell.
Well-maintained trailers are worth more — when you can prove it. TrailerBook keeps the proof attached to the VIN.
- A maintenance plan for your trailer
- Built from your trailer and how you use it. Tap Done when it’s done; at most one reminder email a month.
- Shop-verified records
- Work logged by a registered service shop is marked verified, so buyers know who did it.
- Owner-logged maintenance
- Owners can add their own work and receipts. It's clearly labelled as owner-reported.
- Transfers with the trailer
- When the trailer is sold, its history moves to the new owner. Personal details stay private.
