Bought this tandem axle trailer for cheap. Was a wood deck dovetail lowboy built by trailer mfr in the late 90's. I bought it with no wood floor.
I added a bunch of 2x2" angle iron cross supports one day, then parked it back outside for a few months til I was able to pull it back into the shop. I finished up some of the cross supports that I didn't have a chance to finish, then laid down some 1/8" diamond plate steel for an open center car hauler.
I had the whole thing sand blasted for $100, then I painted it with gloss black enamel. I added new wiring, new lights, new reflectors. Custom receiver/winch mount at front, built some 6' long ramps and ramp pockets underneath. I also put in new bearings, added brakes to one axle, new suspension bushings, and new trailer tires. I sold it a few days after finishing it up because the truck I was driving everyday couldn't pull it ('56 Ford F100).
These pics are from after I welded most of the cross supports in, and after I laid the floors in. I never got around to taking any pics of it all painted up.
Now I need a damn trailer so I have to go buy one. Should have never sold this one!
