A vehicle capable to transport fluids in the built-in tank
Mods introducing new content into the game.
Augmented or new ways of transporting materials - belts, inserters, pipes!

I'm sure there are already mods with large haulers.
There was one I saw but didn't particularly impress me. Your tanker mod did however.
