I think Rivertard has the best looking single axle trailer around.

The best way to make any trailer look good..
Get a decent paint job or have it powder coated (it doesn't have to be totally custom or exotic just clean and shinny)
Wheels/tires (if chromed, no rust... if aluminum, keep polished)
Fender liners (upholster using the same material as the boat, replace when faded)
Lighting (LEDs are cool if you can afford it, but just make sure they all match and all work)
