Thanks Chuck and Jack. The trailer is a full off-road caravan built to near military specs and is capable of going anywhere the tug is capable of towing it. Not big by American standards, but at 19 ft internal, and 3.5 ton, she is big enough for us. These vans were designed for outback and very isolated locations well away from help - hence to two spares.
Evie and I Boondock most of the time so this setup allows us to get into isolated places and often have them to ourselves. We are fully self sufficient with 800 watts of solar, back up gererator, and a water purification system so provided we have access to water, we can go off grid indefinately... I am building up my landcruiser atm to make it a bit more powerful and capable.
If you are so remote you have a Sasquatch ( Big Foot ) swimming close by you are really in the boonies.
My Sasquatch hasn't seen any water for a while and is high and dry in the carport. Still haven't gotten the OK from the Docs to do any paddling.
