Skip,
Don't let my bro see those T90's. He's still talking about the ones he had 35 years ago. The all-purpose, 3rd world motational device. Sips fuel. they made millions of these.
In answer to how we move once we get to camp, it's easy. We don't sprawl enough to make it difficult to just pack up a couple camp chairs and drive the camper to wherever. This is especially convenient in places like Yellowstone or the Grand Canyon or Canyonlands.
We're just a couple crustaceans and it's just as easy to ooze on over to wherever in the box.
