Here's another skid plate idea:
From their description, it looks like a tubular frame with mounting tabs, and a steel plate bolted/screwed to the tubular frame. The tube frame should give it some substantial strength.
They say it fits '98 - '00 Rangers, but I would think that it would fit newer trucks. Their price is pretty steep, but I'm sure you could fabricate one for less, and incorporate a clearance hole for a 2" receiver.
