Yes, I too have this truck, and yes, I really do agree that it is a nicely modeled truck built with techniques that most (A)dult (F)ans (O)f (L)EGO use. (I'm extremly happy to see this present, because not there are not many examples of this since a long time.)
Do you mean the trailer (the huge lunky part) or the nice little cab itself? If you mean you have problems with the roof of the cab not closing, I have that problem also (but only when there is a minifigure inside). If you mean something else, then your theory might be correct, unless other people can help out.
Begining to lose (or have lost) faith in the quality of LEGO parts? Hope this is not the case. :(
If it is, THE END IS NEAR!! *devil*
