OK, so not really a heavy mod... I've always thought the MP-04/JustItToys trailer for the first MP prime was a bit too-stubby and oversized looking. So, I decided to mod an extra MP-10 trailer I got to see how it looked on MP-01. I cut off the front half of the black chassis plate on the trailer bottom (retractable trailer jack stands are still in-place and functional). Stil need to add a hitch peg, paint the trailer rims, and maybe shim the rear wheel assemblies up about 1/16" for more cab-trailer clearance, but it seems to fit ok. Compared to a real semi van trailer, it's a hair too short (height-wise) and not quite long enough like all G1 prime trailers are, but not shabby as a cheaper and different-look MP-01 trailer alternatiive, with the right G1 aesthetics. The MP-10 wheels are actually almost the same size as MP-01, from a side-on view.
