The trailer cargo missions update was amazing but I do have one small problem with the trailers themselves. The problem lies in the wheels that they use, instead of high speed wheels they are currently using all around wheels and this makes pulling them a lot harder for most trucks. During testing I found that the wheel type of a trailer is super important, with high speed wheels on the trailer I was able to comfortably reach speeds up to and above 80km/h which is a realistic speed, at least for European trucks. With all round wheels I was barely able to get it up to 40km/h and the truck that I was using was being pushed to it's limit. I understand that the truck used may have been on the weaker end, but I still believe that this change is important especially given the terrain in game, there are hills that even powerful trucks will struggle climbing with the current trailers.
