Yay, the photos with triple trailers in use! Also, that chapel is a great example of recycling — even the cooling unit is remade into AC system
.
Google has some photos of stationary and mobile versions of these chapels, even some inside photos.
In addition to new car transporter (the current ones may be among the oldest ATS trailers), I think, we need more trucks as a cargo — today we have only two models, and only one of them with different colors.
So, we need more material for playing some scenarios like
«you took the shortest straw, so put these beacons on and pull us!».
For current set of trailers,
ETS allows you to carry more cars at once (6 vs 4), and
ATS — to carry more trucks (3 vs 2)
