Looking for Trailer

[Deuce]

Ideally it would be at least 5x8 actual cargo space and have high sides; basically a big box on wheels that I can outfit with a roof. I want to haul/leave my raft and camping gear in it and occasionally use it for firewood, etc. I've been searching CL and have found some good candidates, but most have been a tad high. Some of you know exactly what I want I'm sure.
