Just tested it, and I think I'm in love!
Only 14MB for the whole pack, great look, no errors that I could see, good road behaviour, and, amazingly, very nice sound pack, better than 98% truck mods out there!
Capacity is 50.000, I might bump that a bit to 56000 since all my harvesters have max capacity 8000L. 8x7=56
And even in the vanilla game there are trailers with more than 50000L.
Thank you for the mod. Finally found the new workhorse for my farms!!
