Write the duty before choosing the chassis
Start with the jobs you intend to accept. List the vehicles, their loaded condition, whether they can roll, the available loading space and the distance to the repair depot. Keep exceptional recoveries in a separate column. Otherwise, a rare heavy job can quietly become the requirement for every truck in the fleet.
The purchase brief should distinguish carrying a whole vehicle, supporting an axle for towing and pulling a vehicle into a loading position. Ask for the equipment and attachment requirements for each duty, rather than one general "recovery capacity". The wrecker module in the buying checklist separates the underlift, winch and deck questions. KEEYAK Buying Checklist, Rev 1.0

| Job to describe | Information to provide | Decision it supports |
|---|---|---|
| Whole-vehicle transport | Vehicle mass, dimensions, ground clearance and loading condition | Usable deck, loading geometry and loaded axle review |
| Axle-supported towing | Target axle load, attachment geometry and target manufacturer towing instructions | Underlift rating at the required reach and towing compatibility |
| Loading with a winch | Whether the vehicle rolls, loading path and the required attachment method | Equipment selection and a task-specific plan by qualified personnel |
| Roadside access | Shoulder width, approach space, recovery destination and traffic-management responsibility | Setup envelope and jobs the proposed truck cannot cover |
Compare the truck after the body and equipment are fitted
Ask for a general-arrangement drawing and a mass schedule that includes the body, crew, fluids, tools and specified accessories. A bare chassis figure is not a loaded wrecker figure. The technical schedule provides fields for these items; have the supplier complete them for the actual build. KEEYAK Technical Data Sheet, Rev 1.0
Miller’s Series 10 manual makes a useful distinction: the carrier rating and the chassis rating both matter, and load placement must respect the chassis axle ratings. This is a design principle to check, not a set of Miller numbers to reuse on a KEEYAK order. Miller Industries Century G2 Series 10 manual, August 2025
Agree on what the inspection must demonstrate
Put the target duty, drawing revision and equipment identities beside the acceptance method. A video of an unloaded deck moving does not answer a question about loaded axle distribution or the underlift rating at a particular reach. Ask for the relevant measurement or approved test record. KEEYAK Inspection Checklist, Rev 1.0
Keep procurement review separate from a live recovery plan. This article does not prescribe roadside positioning, rigging or traffic control. Qualified operators must use the installed equipment manuals, the target vehicle’s instructions and the site controls. Stop if the load, attachment, ground conditions or traffic arrangements cannot be established.
- Record the completed chassis and body identities.
- Review the empty and representative loaded axle measurements.
- Close defects before release and retain the acceptance record.
- Receive the correct operating manual, parts register and training scope.
Roadside recovery: compare each load path
Jerr-Dan publishes a specification for a named 15-ton steel carrier. Use that document as an example of the equipment identity required when comparing offers, not as a rating for a KEEYAK flatbed. Jerr-Dan 15-ton steel carrier specification

| Duty | Document to compare | Acceptance boundary |
|---|---|---|
| Carrying | Deck dimensions, loading angle and rated deck load | Confirm target wheelbase, clearance, restraints and completed axle loads. |
| Pulling | Installed winch identity and line-pull conditions | A winch pull rating is not a carried payload or towing rating. |
| Towing | Underlift chart, extension and attachment limits | Check the supported axle, towed mass, chassis and target vehicle instructions separately. |
