LOL yeah. Actually the MP10 trailer is too big for MPM4, on trucks the trailer should be slightly narrower than the truck's side (extended out) mirrors, as is the MP10 trailer is actually slightly wider than MPM04. Hell, even the UFO trailer is not as wide as the MP10 trailer. Yeah, damn UFO trailer is now too big (and connector not compatible!! ggrrrrrr) GRRRRRR.
