WTB- Tandem trailer in great cond. for a 2000 Red/wht. 20XD

Anyone out there have or know of where I can get a used Bullet Tandem trailer possibly a Hustler chromed out - that's in great shape for a 2000 Red/white 20XD? I have a single axel trailer on it now thats red with the clear coat flaking on it that I'm willing to swap and pay a difference to boot.
or does anyone know whether you can add a additional axle to a single trailer to make it a tandem and just add chrome fenders and whether that'll be cheaper?

If so, what's the smartest way to go about doing it to where everything will line up properly and not cost a ton of money for tire replacement? Secondly, where can you get the parts?
