Free 5x8 trailer minus the tires or $160 with tires(new).  I was going to replace the side rails (as they were rusty) and decking but bought a bigger trailer instead.

Comes with:

aluminum fenders and newer lights. 

large plastic truck chest that you could mount to the front.

bolted on trailer jack

Some sort of monster axle (6 bolt hubs)

Needs:

wiring

Side rails replaced (you could used as it but I would recommend for light weight stuff like brush and mower only,  not hauling big blocks).

Decking

Paint (optional)

Tires. Throw on some cheap 15" car tires and you got yourself a trailer
