yeah i've been considering this as well, always keep an eye out at the junk yard for a good looking truck bed to chop up and use, since the rear suspension and axle should already be attached to the frame, is mr. leary in this thread, i seem to think he has a pretty cool trailer as well, my main question is what's the cheapest and best way to start from? is the truck bed idea a good way to start looking at this? and what's better leaf or coil sprung? and over under or under over shock mount? or does it matter?
