Nice little trailer,

I had never seen one like this before and I can see some advantages of having one, especially the people that go back into woods and back area's scrapping. Also have a single axle model.

Plus they have other options and other variations.

Wow! I've never seen a trailer like that before, and everyone around here has wheelers.

That seems like quite the trailer. I followed the link and they have lots of info on their site. Nice specs to it.
