 # Towbar
 
-Do you want to build a towbar
+Vehicle-to-vehicle tow bars and server-authoritative wrecker controls for
+Project Zomboid Build 42.20.
+
+Portable towbar and wrecker connections persist through solo save/exit,
+dedicated-server restarts, and vehicle-cell streaming. Saved pairs are matched
+with stable vehicle database IDs and reconnected without consuming, refunding,
+or dropping another tow bar during load recovery.
+
+## Supported wrecker mods
+
+Only the listed vehicle scripts receive the seated-driver hook controls. Each
+vehicle must still expose its expected `hook`, `trailer`, and `trailerfront`
+attachments at runtime.
+
+| KI5 mod | Workshop ID | Mod ID | Supported vehicles |
+| --- | --- | --- | --- |
+| '76 Chevrolet K Series | [3161951724](https://steamcommunity.com/sharedfiles/filedetails/?id=3161951724) | `76chevyKseries` | `Base.76chevyC30CCwrecker`, `Base.76chevyC30SCwrecker`, `Base.76chevyK30CCwrecker`, `Base.76chevyK30SCwrecker` |
+| '93 Chevrolet Suburban / Silverado | [3152529790](https://steamcommunity.com/sharedfiles/filedetails/?id=3152529790) | `93chevySuburban`, `93chevySuburbanExpanded` | `Base.93chevySilveradoK3500wrecker`, `Base.93chevySilveradoK3500mechanic` |
+| '78 AM General M35 Series Trucks | [2799152995](https://steamcommunity.com/sharedfiles/filedetails/?id=2799152995) | `78amgeneralM35A2`, optional spawn module `78amgeneralM62` | `Base.78amgeneralM62` |
+
+The ordinary AM General M35A2 and non-wrecker Chevrolet variants are not
+included because their vehicle scripts do not define a tow hook.
+
+## Incompatible mods
+
+`Tow Truck[B42]` (Workshop `3446203945`, Mod ID `STowTruck_B42`) is marked
+incompatible. It owns a competing radial menu, towing state, and vehicle
+constraint implementation, so loading both systems could attach or detach the
+same pair twice.
