This mod was upgraded to FS25 from the original FS22 version by "Landmensch."
It is completely operational and free of faults and console warnings.
These features have been disabled since the original mod made use of the Manure System mod, which is now unavailable in FS25. The tanks may still be used to load and unload liquids, however.
The best option for moving liquids is the top tanks for Unimogs from Modding-Welt and Landmensch.
Because the technology is straightforward and simple to set up, it may be used right away.
