Description:
I edited this mod which i believe was made by alfalfa6945 but not 100% sure. There is a script with the mod not sure who the author was but credit to who ever did it.
any way what did i do , I moved the coupling joint foward as i found it was sitting way to far back and looked wrong.
It seemed that alfalfa6945 had the connection joining at the front on the trailer so i just moved it back to what i think is where it should be, Tension belts are a little buggy i don't know if its this mod or another one i have conflicting but the tension belts don't seem to wrap around the items sometimes  , but they do seem to hold them in place
Any way the load and unload does work they are just a little fiddly.

To load you need to press the U key after you select what you want to load i.e Pallets or bales and then press U to turn work mode to off and drive upto the pallets or bales and they should load.
To unload make sure work mode is on ( press U key ) and then press the B key a new menu will pop up with the unload functions.
hope you like the mod and modification i did.
