I built this trailer originally to tow my 14ft catamaran and have it be legal.
it has two different modes where the drawbar can be extended by undoing a few bolts and repositioning it.
I built it as light as I could with aluminium panels on the sides considering the Sierra's awful towing capacity.
It has sierra front free wheeling hubs complete with brakes and calipers.
I built solid 10mm plates for the hub to bolt to, you can unbolt it from the trailer and bolt it straight onto a sierra, the idea being if you were in the bush its better to leave the trailer behind than be stuck.
It is also narrow, it was just shy of the same width as my old sierra.
The trailer is also fully registered for nearly another year
The sides can come unbolted and detached to make it a flat bed trailer.
It has LED lights all around with clearance lights on the flares.
Lifted axle for clearance.
the brake lines from the hitch to the brakes need to be connected but they are brand new and professionally made, the brakes make noise at the moment but that is a bit of rust on the disks, the plywood bottom is a bit warped but doesn't change the function. the hinges to the front and back sides which fold down are rusted solid so they need to be ground off and replaced... depending on your situation and a bit of bargaining i may be able to fix these if it's an issue.
I'm looking for $600 ono
