Offroad Travel Trailers in the US?

While we'd still love an offroad capable trailer, most of what we found was lacking. So... we went exact opposite direction and picked up a lowrider 30' airstream. We've got the van for when we want to get off the beaten path, and it'll go places even the australian trailers won't go.

Since we're going to live in it full time and work from the trailer, we opted for more space.

We videod the journey of picking up our Airstream. It was quite an exciting day!
