The Mack Ultraliner is one of the most recognizable cabover trucks in American trucking history. Its rugged design, flat-front cab, and distinctive appearance made it a familiar sight on highways and freight fleets throughout the 1980s and 1990s. This mod brings that same character to American Truck Simulator, faithfully recreating one of Mack’s most iconic models.

The mod features a carefully crafted exterior and interior, delivering a classic cabover driving experience for players who appreciate vintage trucks. Every detail has been designed to capture the look and feel of the original Ultraliner while preserving its unique identity within ATS.

Main Features
Detailed Mack Ultraliner cab.
Functional interior faithful to the original design.
Two chassis configurations.
Various engine and transmission options.
Extensive customization possibilities.
Predefined & custom paints and accessories.
Vehicle-specific sounds.
Compatible with current versions of American Truck Simulator.

One of the Ultraliner’s most distinctive characteristics is its cabover layout, with the cab positioned directly above the engine. This design provides a different driving experience compared to conventional trucks while maintaining the classic appearance that made the Ultraliner so popular among trucking enthusiasts.

This is a Lite version of the mod. To obtain the Full version with all features, accessories, customization options, and additional content, please visit the Gumroad link or contact me by email (cyrusthevirus2016@gmail.com).

– Engine sounds added to the 2017 DAF XF 106 in AI traffic (PACCAR MX-13 480 hp and 560 hp configurations). [ETS2 edition]

DESCRIPTION
===========

This mod has been bringing more immersion to common sounds in the game for over 10 years!

It packs a variety of sound content within one mod, making it great value within the 100 mod limit in Convoy multiplayer.

COMPATIBILITY
=============

* ETS2 1.59.1 + ATS 1.59.2. No errors in game log. Must have high priority in Mod Manager.
* Does not replace individual player truck sounds, so this mod can be used with an unlimited amount of truck sound mods of your choice.
* Compatible with all maps and all trucks, including truck mods.
* Supported in single-player and multiplayer Convoy mode, and is marked as an optional mod in Convoy.

MINIMUM REQUIREMENTS
====================

Requires higher priority in Mod Manager than:

* any map mods (e.g. ProMods)

FEATURE LIST
============

The mod features meticulously crafted sounds, covering the following:

* Suspension and tire bump sounds for your truck and trailer.
* Reworked fuel / filling station sounds.
* Extended sequence of sounds for after refueling, such as the door close and putting on the seatbelt.
* Train sound enhancements for several locomotives and railroad cars.
* Country/state specific railroad crossing bell sounds.
* Rain and thunder sound overhaul, including significant additional weather based features such as wet tire sounds.
* The most complete tire sound package for all terrains: asphalt, gravel, grass, snow, and sleeper lines.
* Reworked tire screech/skid sound effects.
* Door open and peeling of protective plastic film sounds for the cutscene of a newly purchased truck.
* Nokia phone ringtone sound replacing the hurry up / late music, leading to less stress for the player.
* Default common sound reworks, such as improved default air brake sounds.
* AI traffic vehicle sound improvements, with engine and horn sounds uniquely set for hundreds of specific vehicles.
* (ETS2 only) Several countries supported with local police siren sounds.
* English AU/UK/US voice navigation variants with speaker effect added and uncustomary phrases removed.
* Wind buffeting and rush of air sounds at high speeds only when the window is open.
* More environmental and ambient sounds, and tasteful changes to existing ambient sounds in the game world.

* Extended sound sequence for the hooking and unhooking of semi-trailers.
* 8 standalone air horns.
* Default gear grinding sound effect additions and improvements.
* Enhanced reverb zones, including stronger reverb when under bridges and overpasses.
* (ATS only) Drawbridge lift warning sound for the Columbia River Interstate Bridge.
* (ATS only) Working sounds for the Musical Road on the Historic Route 66.
* (Optional) Reefer / refrigerated trailer sound functionality.
* (Optional – ATS only) Cop scouting reports via CB radio (enable in voice navigation options).
* Multiple sound bug fixes for the vanilla game and/or mods.
* A couple of UI sound replacements in the Driving Academy module.

For further immersion, the mod may also include official paint colors and more authentic specifications for each AI traffic vehicle it modifies for sound. Rarer paint colors are less likely to be seen.
