Powerful UK may already be working on a "MOLLE" aluminum plate for LR3/4, similar to the one they recently designed for the new Defender. Only issue I see is that the Defender already comes with receptacles for the mounting bolts and spacers under the trim below the rear windows (which are used for ladders and lunch boxes), LR3 and 4 probably don't. It's very sturdy, lightweight and closely hugs the bodywork. Zero wind noise (unless you hang stuff on it), and Rotopax / Maxtraxx mounts are apparently coming soon.
