Geoff, looks great but your tandem trailer looks too clean and newish. Bit like a Toorak Trailer;D
Here's a genuine offer to help ya. Bring it along into Mt Disappointment next time Fuji and I head in. We'll fill our chainsaw fuel and oil while balancing on the side. Spilled oil and fuel is really great for capturing forest dirt and dust. Make it look a whole lot tougher!
Then we'll load it with mountain ash logs freshly cut and dropped in from the side. Add a few dents, scrapes and paint chips. Starting to look really rugged now.
Then we'll get you to follow us the a few gravel tracks and maybe a creek wash out. That'll fix those shiny alloy rims. By the time we've finished and dropped the timber at our places, it'll look like a real trailer.
It's ok, don't thank us for the offer. That's what myswag friends are for;D
