Started with a poor example, bought on ebay. As mentioned, the aim was to have a capable off road trailer.
Got it home, took some more photos, and it looked even worse. You could see through the floor, the tub mounts were rusted off. As original, the tub is watertight. It came from a tropical location, and as expected, the tub filled up with water - and rusted. Some kind soul (but misled)tipped the water out and turned it upside down. Now the water pooled under the lip of the trailer.
Anyway, that weekend it was brought home and sandblasted. That's the worst it's looked at that point..
The finished product, as it stands today.
