To boldy go where no camper has gone before...

Trailer is nothing special other than the tires and a axel under spring swap. Looks like they made the tow vehicle and trailer tires the same size so they can share spares, Good idea. Any vehicle can do that trip, just need to set it up right. That Toyota had lockers in it so that makes a huge difference. No lockers and it would not have done most of that rough stuff.
