Could a truck have a bunk over the Cab?

I personally like the look of a lot of euro trucks. I like the skirting that you see on most of them creating a low profile.

Is that a pintle on the front of the one pictured here? would it be used to tie multiple of these together?

 

i dont like look of this one very uncomfortable for driver ( very short cab very small possibilitys for adjusting seat...)

on this one engine is not below cab ( because engine is too long for this ca)

engine is placed between axles ,in those years mercedes used their specially build v6 to be shortest as possible )

this ringfeder in front of truck is used to maneuvering drawbar trailers -this truck is used by "amusement park"


most of their trucks have this or smaller hook instead of ringfeder

also their tractors have hook at rear to be able to tow longest possible trailers
