It's a MUTS, made by a guy just a couple of hours away from me:
MUTS - Multi-Use Trailer System for your ATV, Quad and 4 Wheeler. A very similar one is
Multilander™
They do sell to/ship to the US, but thanks to tariffs and transborder shipping bureaucracy, the prices go up quite a bit.
A friend from the US who really liked mine eventually bought a
Trailer ECO 1000 from a local dealer near him for less.
We really like it, especially:
- The stepped profile keeps centre of gravity low
- The tandem ATV wheel axles tilt indepedently so it can "walk" over rocks and small logs
- Well balanced, can be rotated and pulled (empty and not up hill) by human force
- The manual winch and mast work decently to lift the dump bed or to pull stuff up into it, with reasonable expectations (whaddya know, our tractor logging winch is more powerful than a human turning a crank...)
Our model is rated for 2000 lbs cargo capacity, some of the others for less (1000 lbs?). We've maxed out UTV/ATV power, and more importantly safe braking capacity, in our hilly terrain much earlier. Don't try to fill it all the way with gravel and expect to pull up a hill, or dump with the manual winch!
