Here's one I've never heard of....Sports-Cam fiberglass

In a way, putting a TC on a flatbed trailer is an interesting idea I'd never considered before. One can get the TC to sit lower than it would in a pickup bed, so fuel economy would be a little better. With a somewhat longer tongue than the one pictured, the TC could be towed by an SUV. Hitch weight could be easily adjusted by varying the load position forward or back. And one could tow a heavier TC with a 1/2 ton pickup than the pickup could carry.
