UK S.Pioneer TRMU30 Truck/Trailer

[JG26_EZ]

S~ all

I see that building a single scene is going to take quite alot
of work compared to what we we've had with IL2:1946.
Still a rookie mission builder in Cliffs of Dover I guess..

I'm trying to create a static situation with the "static"
allied truck and trailer this time, and have run into a whole
new collection of problems.

Must/Can I "attach" these two somehow to "make ends meet"?
Or perhaps a way to level the trailer out?
