Avia A15/30 trucks were produced in Czechoslovakia from 1968 to 1983. It was a licensed copy of the French Renault-Saviem SG4 car. Designed for 1.5/3.0 tons of cargo, the car had two main options: an on-board truck and a universal chassis in three variants:

- Short-base (with the prefix K);
- Long-base (L) and normal (N).

A lighter (single-pitched wheels) version of the truck was called "Avia" A15.

Avia A15/30 (Fillable) transportation of bulk materials.

- Added popular FS19 options/configurations, with the exception of chassis animation (gimbals, springs, springs, steering).
- Support for the script "Real Dirt Color", "Enhanced Vehicle", "Real Ground" (from OTK).
- Works with "CoursePlay", tested on version v6.5.0.0, without comments. AutoDrive has not checked, but it should work.
- Fixed AI (AI) collisions, now "CoursePlay" does not issue errors in the log.
- Added the script "Different engine sounds" (2 motors with individual sounds to choose from).
- General edits (XML registration, physics, sounds). Fixed minor bugs (turn signals, lights).
